Question

  A particular state computed income tax, T (in dollars) on a person’s income, x (in dollars), by the following formula:

T(x)=(0.018x if 0 ≤x≤5,000

90+0.025(x-5,000) if 5,000<x≤10,000

215+0.050(x-10,000) if x>10,000)

a.      What is the tax on an income of $7,300? Show work.

b.     (b) What is the tax on an income of $73,000? Show work.

Answer 1

for 7300 use the formula 90+0.025(x-,000) if 5,000<x≤10,000

90 +0.025(7300-5000) = 90 +0.025*2300 =90+57.5= 147.50

for 73000 use 215+0.050(x-10,000) if x>10,000)

215 +0.050(73000-1000) = 215 + 0.050*63000 = 215 + 3150 =3365
