Self Checkout

Working with multiple inputs and currency can introduce some tricky precision issues.

Create a simple self-checkout system. Prompt for the prices and quantities of three items. Calculate the subtotal of the items. Then calculate the tax using a tax rate of 5.5%. Print out the line items with the quantity and total, and then print out the subtotal, tax amount, and total.

Example Output

 Enter the price of Item 1: 25
 Enter the quantity of Item 1: 2 
 
 Enter the price of Item 2: 10
 Enter the quantity of Item 2: 1

 Enter the price of Item 3: 4
 Enter the quantity of Item 3: 1
 
 Subtotal: $ 64.00
 Tax: $ 3.52
 Total: $ 67.52

Constraints

• Keep the input, processing, and output parts of your program separate. Collect the input, then do the math operations and string building, and then print out the output.

• Be sure you explicitly convert input to numerical data before doing any calculations.

Constraints

• Use a single output statement.
