Design an algorithm and draw a flowchart for a company that sells three types of balls: tennis ball (T), billiards ball (B), and rugby ball (R). They sell for $5.00, $7.50, and $10.00 respectively. This algorithm should read two inputs by the user. The first input should be a letter (T or B or R) indicates which type of ball customer want to order. The second input should be a number indicates how many balls the customer has ordered. It should then calculate and print to the screen the total cost of the balls, the sales tax charged at a rate of 7.5% and the total sale including sales tax.
