Mr Asiedu earns an annual salary of GH6000.00. His total allowances is GH2000.00.How much tax does he pay if the rate of tax is 15%
Answer:
GH 1200
Step-by-step explanation:
Salary = GH6000
Allowances= GH2000
Taxable income = (Salary + Allowances)
Taxable income = GH6000 + GH2000
=GH8000
Tax rate = 15%
Tax = GH8000 X 15/100
= GH 1,200

The age of the father is 42 and the age of the son is 9. At what age, will the father be twice old as the son?
(Solve by equation system.)
Answer:
24
Step-by-step explanation:
42 + x = 2 (9 +x) (solve for x)
42 + x = 18 + 2x
42 -18 = 2x -x
24 = x
42 + 24 = 66
9 + 24 = 33
When the man turns 66, his son will be 33, or half his age.
