Question

Joe filled his gas tank four times last week. here are the amounts he bought (in gallons); 12.73, 13.01, 13.33, and 11.33. How many total gallons did he buy? what was the average purchase?

Answer 1

To get the total number of gallons, you add the amounts he bought together. So, the total is 12.73 + 13.01 + 13.33 + 11.33. This equals 50.40 gallons. To get the average purchase, take the total and divide by the number of times he filled his gas tank. The total is 50.40 gallons and he filled the tank 4 times. So 50.40 / 4 = 12.60. Therefore the average purchase is 12.60 gallons.
