Question

A single person pays $4,500 in income taxes on a gross income of $30,000. How much would a single person be expected to pay if his gross income is $32,000? (Assume both incomes are in the same tax bracket.)

Answer 1

4500/30000 =0.15

32000 * 0.15 = 4800

Answer 2

T/32000=4500/30000, multiply both sides by 32000

t=32000*4500/30000

t=144000000/30000

t=$(14400/3)

t=$4800
