Objective

Calculate a tip amount and a bill total from a subtotal and a tip percentage.

Terms

• Subtotal — the cost of your food and drink
• Tip (gratuity) — additional payment given for a service
• Total — the sum of the subtotal and the tip

A $10 bill with a 20% tip is a $2 tip and a $12 total. A $25 bill with an 18% tip is a $4.50 tip and a $29.50 total.

Skills to Practice

• Prompting a user for input
• Saving user input to variables
• Converting input to the correct data type
• Performing arithmetic calculations
• Formatting custom output using variables

Tasks

• Create a new Python program named cc-tip-calculator.
• Prompt the user to enter the bill subtotal.
• Prompt the user to enter the tip percentage as a whole number — 20 means 20%.
• Calculate the tip. Formula: Tip = Subtotal × (Percentage ÷ 100)
• Calculate the total.
• Display the tip and the total in a clear, formatted way.
• To always show two decimal places on a dollar amount, look up how string formatting works in Python.

Sample Output
