Question

You found an exciting summer job for five weeks. It pays a set amount per hour (for example, $15.50). Suppose that the total tax you pay on your summer job income is 14%. After paying the taxes, you spend 10% of your net income (income after taxes) to buy new clothes and other accessories for the next school year and 1% to buy school supplies. After buying clothes and school supplies, you use 25% of the remaining money to buy savings bonds. For each dollar you spend to buy savings bonds (rounded down), your parents spend $0.50 to buy additional savings bonds for you. Write a program that prompts the user to enter the pay rate for an hour and the number of hours you worked each week. The program then outputs the following:

Your income before and after taxes from your summer job.

The money you spend on clothes and other accessories.

The money you spend on school supplies.

The money you spend to buy savings bonds.

The money your parents spend to buy additional savings bonds for you.

The remaining income after expenses and investments.

create a small test plan for your finished product with at least 4 cases.
