Chapter 9.7, Problem 33P

In the country of Taxo, each household pays taxes on its annual household income as determined by the following:

• A household with income between $0 and $20,000 pays no tax.
• For each $1 of income beyond $20,000, and up to $50,000, the household must pay $020 in tax.
• For each $1 of income beyond $50,000, and up to $100,000, the household must pay $0.40 in tax.
• For each $1 of income beyond $100,000 the household must pay $0.60 in tax.

This situation gives rise to a tax function in which the input is annual household income and the output is the taxes paid;

a. Make a table for the tax function.

b. Draw a graph of the tax function.

c. Is there a single equation for the tax function?
