JAVA, Write algorithms using pseudocode and draw the flowcharts for the following problems. Example: a) Calculate the total of a retail sale.

Ask the user for the following:

• The retail price of the item 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 bill

Example: If the sales tax rate is 7%, compute 7% of the purchase, add it to the total purchase that would be total of bill.

Total of bill = purchase + 7% of purchase

b) Decide if credit is available

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 the customer's available credit by subtracting the amount of credit used from the maximum amount of credit. The program should print out "no more credit available" if the available credit is less than zero or print "credit available" if the available credit is greater or equal to zero
