A. Sarah's bill at the restaurant was $12.81. She left a tip of 20%. What was the tip amount? Round your answer to the nearest hundredth. B. What was the total bill? Round your answer to the nearest hundredth.

A. $2.56

B. $15.37

Step-by-step explanation:

A. When you’re asking what is a certain percent of a specific number, you turn the percent into a decimal and multiply it by the specific number. In this case, 0.20 * 12.81 = 2.562

Since we are to round to the nearest hundred, that leaves us with $2.56.

B. To get the total bill, add 12.81 and 2.56 to get a total of $15.37.
