Ezra spent $60 on gas each week for a period of three weeks. The first week gas was $3 per gallon, the second week it was $4 per gallon, and the third week it was $5 per gallon. What was the average amount Ezra paid per gallon of gas over this three-week period? Express your answer as a decimal to the nearest hundredth.

Week 1:

3$/gallon, 60 total, so 60/3 = 20 gallons.

4/gal, 60 total, 60/4 = 15 gal.

5/ gal, 60 total, 60/5 = 12gal.

Adding 20+15+12 = 47 gal.

Divide this by 3 weeks = 15.666666666666667

So rounded is 15.67
