8-50.

Autumn and her friends had dinner at their favorite restaurant, and the bill came to $60. They decided to leave 18% of the bill for a tip. Without using a calculator, help them compute how much money is 18% of the bill. Homework Help ✎

10% of $60 is $6.
5% of $60 is $3.
1% of $60 is $0.60.
Can you combine these to find 18% of $60?
Can you find more than one way?

You can see 18% as 10% + 5% + 3(1%) or as 2(10%) – 2(1%).
