A cell phone provider has three different subscription packages for its customers:

Package A: The monthly cost is $29.99 and there are 300 available minutes as part of the package for each month. Any additional minutes are $0.32 per minute.

Package B: The monthly cost is $49.99 and there are 750 available minutes as part of the package for each month. Any additional minutes are $0.28 per minute.

Package C: The monthly cost is $59.99 and there are an unlimited number of available minutes.

For this assignment, write a program that will calculate a single monthly bill for a customer.

Basic Program Logic

Prompt the customer for the package that they subscribe to for the month. This is a character value and the possible values are 'A', 'B', or 'C'. For this assignment, assume that the customer will enter a valid subscription package.

Prompt the customer for the number of minutes that they used during the month. This is an integer value that should be 0 or positive. If the customer enters an invalid value, display an error message and get another value from the customer. For this assignment, assume that the customer will enter a valid number of minutes the second time.

Based on the package and number of minutes used during the month, calculate and display the monthly bill amount for the customer.

Program Requirements

The calculated bill amount should be displayed with exactly 2 digits after the decimal point and a leading dollar sign.
