Chris works at an electronics store. He earns $10 per hour plus 12.5% commission on his computer sales. Today, Chris worked 5.5 hours and sold $1100 in computers. How much did Chris earn in total today?
Answers
By solving a simple equation we can see that Chris earned $192.50.
How much did Chirs earn Today?
We know that Chris wins $10 per hour plus the 12.5% of the total amount he solds in computers.
So, if he works 5.5 hours and sold $1,100 in computers, the amount that he earns is given by the equation:
E = $10*5.5 + $1,100*( 12.5%/100%)
E = $10*5.5 + $1,100*(0.125) = $192.50
Then we conclude that Chris earned $192.50 today.

Last week, the total weight of the members of a weight loss support group was 2,500 pounds. This week, it was 2,525 pounds. What percent heavier is the group now? %
Answers
The percent increase from 2,500 pounds this week to 2,525 pounds is 1% increase
How to find the percent increase of the weights?From the question, we have the following parameters that can be used in our computation:
Initial weight = 2500 pounds
New weight = 2525 pounds
The percentage increment is then calculated as
Percentage = (Final value - Initial value)/Initial value * 100%
Substitute the known values in the above equation
Percentage = (2525 - 2500)/2500 * 100%
Evaluate the difference
So, we have
Percentage = 25/2500 * 100%
Evaluate the quotient
So, we have
Percentage = 0.01 * 100%
Evaluate the product
So, we have
Percentage = 1%
Hence, the percent increase is 1% increase

11. Corey bought 25 gallons of gas to fill up his pickup truck. He paid for the part of the total with a $25 gift card and was left owing $26. How much did he pay per gallon for the gas?
Answers
Answer:
I believe that the answer is $2.04, per gallon.
Step-by-step explanation:
I added the $25 he paid with the gift card, and the $26, which was $51 that Corey paid in total. Corey had gotten 25 gallons and they want to figure out how much he paid for each gallon. So we take the total he spent divided by the number of gallons he had gotten. So 51/25=2.04

What should be added to 5/6 to get 41/24
Answers
Answer: 26/24
Step-by-step explanation:
First we have to convert 5/6 with a denominator of 24 so 6 times what makes 24, that is 4 & whatever you do with the denominator, you have to do it with the numerator. So 5 times 4 is 20, the new fraction is 20/24. Now, we need to find what we need to add with 20/24 to get 41/24, so we subtract 20/24 from 41/24 & that is 21/24. We can check if it's correct by adding both 21/24 and 20/24 & that makes 41/24.
5/6 + x = 41/24
x = 41/24 - 5/6
x = 41 - ( 5 multiplied by 4) / 24
x = 41 - 20 / 24
x = 22 / 24
x = 21/3 / 24/3
Final answer x = 7/8
Which ordered pair is a solution of the equation? 2 x + 4 y = 6 x − y 2x+4y=6x−y
Answers
The solution to the equation given as 2x + 4y = 6x − y has the ordered pair of (3, 4)
How to determine the ordered pair of the solution?From the question, we have the following equation that can be used in our computation:
2x+4y=6x−y
Solving further, we need to collect the like terms
So, the equation becomes
2x - 6x = -4y - y
Next, we evaluate the like terms in the above equation
So, we have the following representation
-4x = -3y
Divide both sides by -3
The equation becomes
x = 3/4y
At this point, we assume any value for y and then solve for x
Assume that the value of y is 4
So, we have the following representation
x = 3/4 * 4
Evaluate the products
x = 3
So, we have
x = 3 and y = 4
Express as ordered pairs
(x, y) = (3, 4)
Hence, the ordered pair of the solution is (3, 4)

A sample of size 39 will be drawn from a population with mean 23 and standard
deviation 10. Find the probability that will be greater than 25.
Answers
The probability that X will be greater than 25 is 0.42
Given,
The sample size, n = 39
The mean of the population, μ = 23
The standard deviation of the population, σ = 10
We have to find the probability for X > 25.
Here,
Z score = (X - μ) / σ
Z score = (X - 23) / 10
Now,
We have to find P(X > 25)
Then,
P(X > 25) = P(z > (25 - 23) / 10)
P(X > 25) = P(z > 2/10)
That is,
P(X > 25) = P(z > 0.2)
Here,
0.5 - P(0 ≤ z ≤ 0.2)
= (0.5 - 0.0792)
= 0.42
Therefore,
The probability that X will be greater than 25 is 0.42

What is Arithmetic Progression and Geometric Progression?
An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The general form of a GP is a, ar, ar2, ar3 and so on
Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
Given data ,
First term = -2
Second term = 4
A)
For Arithmetic Progression
First term a = -2
Second term = 4
Common difference d = Second term - First term
= 4 - ( -2 )
= 6
And Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
n = 10 terms
Sₙ = ( 10/2 ) [ (2x- 2) + ( 9 ) x 6]
Sₙ = 5 [ -4 + 54 ]
Sₙ = 5 x 50
Sₙ = 250
Therefore , Sum of first 10 terms of an AP is 250
B)
For Geometric Progression
First term a = -2
Second term = 4
Common ratio = Second term / First term
= 4 / -2
= -2
And Sum of first n terms of an GP : Sₙ = a( 1 - rⁿ ) / ( 1 - r )
n = 10
Sₙ = 2( 1 - ( -2 )¹⁰ ) / 1 - ( -2 )
Sₙ = 2 ( 1 - 1024 ) / 3
Sₙ = ( 2 x (-1023) ) / 3
Sₙ = 2 x ( - 341 )
Sₙ = - 682
Therefore , Sum of first 10 terms of an GP is -682
The difference between the sum of first 10 terms of AP and GP is GP - AP
= -682 - 250
= -932
Hence , The difference between the sum of first 10 terms of AP and GP where the first term and second term is 2 and 4 respectively is -932

The area of the water's surface is given by this expression: w² - w - 6.
Question
Question 1
Factor the area expression, w² - w - 6.
Replace the values of A and B to write the expression in factored form.
(w - A) (w + B)
Answers
After factorization we get the two terms ( w - 3 ) ( w + 2 )
And the values of A and B as 3 and 2 respectively .
That is A = 3 and B = 2.
The given expression is w² - w - 6.
This question can be calculated easily by middle term split
First step is to multiply the first and the last term
which will give us - 6
thus now we have to look for two number which when either added or subtracted will give us - 1
Thus we can write it as :
w² - 3 w + 2 w - 6
Now take the terms which are common
and we will get
w ( w - 3 ) + 2 ( w - 3 )
( w - 3 ) ( w + 2 )
Thus if we compare it with (w - A) (w + B)
we will get the values of A and B as
3 and 2 respectively .
That is A = 3 and B = 2

Lorna Hall’s real estate tax of $2,010.88 was due on December 14, 2017. Lorna lost her job and could not pay her tax bill until February 27, 2018. The penalty for late payment is 61/2% ordinary interest. (Use Days in a year table.)
a. What is the penalty Lorna must pay? (Round your answer to the nearest cent.)
b. What is the total amount Lorna must pay on February 27? (Round your answer to the nearest cent.)
Answers
a) The penalty Lorna must pay for the late payment of her real estate tax is $26.50.
b) The total amount Lorna must pay on February 27 is $2,037.38.
How is the penalty for unpaid taxes computed?The penalty for unpaid taxes is computed by determining the number of days the taxes remained unpaid.
Then the penalty rate is applied to the unpaid taxes multiplied by the number of days taxes were outstanding, divided by 365 days.
The product of the above multiplication and division operations is the penalty.
Outstanding real estate tax = $2,010.88
Due date for the tax = December 14, 2017
Payment date for the tax = February 27, 2018
