Question

A certain country taxes the first $20,000 of an individual's income at a rate of 15%, and all income over $20,000 is taxed at 20%.
a. Al makes $16,000. Betty makes $36,000. How much is each taxed?
b. Write a piecewise function T that specifies the total tax on an income of x dollars.
c. Catina is taxed $5000. What is her income.

Answer 1

if i </= 20,000
tax = .15 * i

if i> 20,000
tax = 3,000 + 0.20 ( i - 20,000)

Answer 2

does the i mean income?

Answer 3

yes, use x

Answer 4

so what would be your piecewise function for B?
