Problem 3

Trish at Bargain Used Books has decided to add a discount program for her loyal customers and for customers that buy a lot. Here's how it works:

• If a customer is in her loyalty program and buy $75 or less, they get a 20% discount.
• If a customer is in her loyalty program AND they buy over $75, they get a 30% discount.
• If a customer is not in her loyalty program but they buy over $75, they get a 10% discount.

With every purchase, Trish also must charge 7% sales tax on the total AFTER any discount.

Create a file named Lab02P3.py. Write a program that calculates the cost for the total purchase:

• Ask the user to enter the total purchase amount.
• Ask the user if the customer is in the loyalty program (see sample output).
• Calculate the total after discounts
• Calculate the amount of sales tax on the total.
• Calculate the total after discounts and tax.
• Output the total after discounts, the sales tax, and the total after discounts and tax. The program should format all money amounts that are output with 2 digits after the decimal point.

Sample Outputs:

Enter the total purchase amount: 80

Is the customer a loyalty program member (y/n): n

Total after discount: $72.00

Sales tax: $5.04

Total after tax: $77.04

Total after discount: $63.00

Sales tax: $4.41

Total after tax: $67.41
