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%).
