Write pseudocode algorithms for the programs described as follows:

1. Available Credit

A program that calculates a customer’s available credit should ask the user for the following:

• The customer’s maximum amount of credit

• The amount of credit used by the customer       

Once these items have been entered, the program should calculate and display the customer’s available credit. You can calculate available credit by subtracting the amount of credit used from the maximum amount of credit.

2. Sales Tax

A program that calculates the total of a retail sale should ask the user for the following:

• The retail price of the item being purchased

• The sales tax rate       

Once these items have been entered, the program should calculate and display the following:

• The sales tax for the purchase

• The total of the sale  

3. Account Balance

A program that calculates the current balance in a savings account must ask the user for the following:

• The starting balance

• The total dollar amount of deposits made

• The total dollar amount of withdrawals made

• The monthly interest rate

Once the program calculates the current balance, it should be displayed on the screen.
