During the tax season, every Friday, the J&J accounting firm provides assistance to people who prepare their own tax returns. Their charges are as follows:

If a person has low income (<= 25,000) and the consulting time is less than or equal to 30 minutes, there are no charges; otherwise, the service charges are 40% of the regular hourly rate for the time over 30 minutes.

For others, if the consulting time is less than or equal to 20 minutes, there are no service charges; otherwise, service charges are 70% of the regular hourly rate for the time over 20 minutes.

Write a function that prompts the use to enter the hourly rate, the total consulting time, and whether the person has low income. Write another function to calculate the billing amount based on this input. Write a driver to test your program. Make your driver loop so that you can enter test data for:

low income, < 20 minutes

low income, > 20 minutes

high income, < 20 minutes

high income, > 20 minutes.

Hand calculate the expected results using your test data and verify that your program produces the expected results.

Source code must include following steps.

Analysis at the top of the file including your test data sets and predicted results.

Function analysis, preconditions, and postconditions after each function prototype
