a) A furniture store can sell 40 chairs per week at a price of sh. 80 each. The manager estimates that for each and sh. 5 price reduction, she can sell five more chairs per week. The chairs cost the store sh. 30 each. If x stands for the number of sh. 5 per price reduction, find price of the chairs and the quantity that maximize profit.
The price of the chairs and the quantity that maximizes profit is to sell 45 chairs at $75 each.
ProfitGiven that a furniture store can sell 40 chairs per week at a price of $80 each, and the manager estimates that for each and $5 price reduction, she can sell five more chairs per week, and the chairs cost the store $30 each, to determine the price of the chairs and the quantity that maximize profit, the following calculation must be made:
40 x (80-30) = 200045 x (75-30) = 202550 x (70-30) = 200055 x (65-30) = 1925Therefore, the price of the chairs and the quantity that maximizes profit is to sell 45 chairs at $75 each.

What is the price of a two year bond with a 9% annual coupon and a yield to maturity of 8%? 101.78 105.25 102.53 97.51
The bond price 101.78
What is the price of a bond?
A bond price is the present value of its future cash flows discounted at the yield to maturity which is the appropriate discount rate.
Specifically, the bond price is the present value of annual coupons for 2 two years and the face value discounted at the 8% yield to maturity.
We can determine the bond price using the present value formula of a single cash flow for all cash flows.
PV=FV/(1+r)^N
FV=future cash flow(annual coupons for 2 years and face value)
annual coupon=face value*coupon rate
face value=100
coupon rate=9%
annual coupon=100*9%
annual coupon=9
r=discount rate=8%
N=year of cash flows, 1 for year 1 and 2 for year 2
bond price=9/(1+8%)^1+9/(1+8%)^2+100/(1+8%)^2

Expand the function
f(x) = 2x^2 + 8x- 6x – 24.
Factorize the function
f(x) = 2x(x + 4) - 6(x + 4)
Factor out x + 4
f(x) = (x + 4)(2x - 6)

Answer: B
Step-by-step explanation: Since x is less than 7, the graph would be all real numbers that are less than 7, so the arrow would be on the left.
Also, since x is not 7 itself (not less than or equal to), the dot cannot be a full dot. Thus, the dot must be open (or curved in some textbooks) to indicate x is not apart of 7 but less than 7.

$1045 was invested at the interest rate 6% whereas $1,995 was invested at 14%
How is interest computed?
Interest is determined as the amount invested multiplied by the interest rate.
Let Y be the amount invested at 6%
Interest=Y*6%
Interest=0.06Y
The amount invested at 14%, which is $950 more , is Y+950
Interest=(Y+950)*14%
Interest=0.14Y+133
Total interest =0.06Y+0.14Y+133
Note that total interest is 342

In Economics, profit can be defined as a measure of the amount of money generated when the selling price is deducted from the cost price of a good or service, which is usually provided by producers.
This ultimately implies that, all producers of any product generally work to maximize their profits and make them as large as possible, in order to enable them break even and successful.
Based on the information provided, we can logically deduce that this function has its roots at x = 0 and x = 26 and its vertex is a minimum. Thus, this quadratic function which describes the relationship between the number of products produced and the overall profit margin is an increasing function:
0 < x < 26, f(x) < 0, which implies a negative profit is generated when between 0 and 26 items are produced.x > 26, f(x) > 0, which implies a positive profit is generated when more than 26 items are produced.x is equal to 26 is the break even point.Therefore, once they hit 26 items they break even again. The worst case scenario is that they produce 13 items, as they will have a profit of -50 dollars because the minimum point is at (18, -35). Also, the first root tells us that the profit will be 0 when 0 products are sold.
