Problem 4

Trish at Bargain Used Books has hired you to write a Python program that will help her calculate what a customer should pay. She has a very simple price structure:

• Paperback books are $2.50 each.
• Hardback books are $7.00 each.
• Magazines are $3.95 each.

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

Create a file named Lab01P4.py. Write a program that calculates the cost for the total purchase:

• Ask the user to enter the number of paperbacks, hardbacks, and magazines being purchased.
• Calculate the total before tax.
• Calculate the amount of sales tax on the total.
• Calculate the total after tax.
• Output the total before tax, the sales tax, and the total after tax.

NOTE: Your program code should implement these steps IN THE SAME ORDER as listed above.

All monetary values should be output with a precision of 2 digits after the decimal point. You should use what was presented in this lesson to achieve that result.

----------------------------------------------------------

Sample Output:

Enter the number of paperback books: 3

Enter the number of hardback books: 2

Enter the number of magazines: 4

Cost before tax: $37.30

Sales tax: $2.61

Cost after tax: $39.91

In your program, besides the header comment, add three additional comments:

• A comment that identifies where the input steps begin
• A comment that identifies where the processing steps begin
• A comment that identifies where the output steps begin.
