The odometer in Mr. Matthews's car does not work correctly. The odometer recorded 15.2 miles for his last trip to the hardware store, but he knows the exact distance traveled is 12 miles. What is the percent error? Round your answer to the nearest whole percent.

Step-by-step explanation:

the odometer read 15.2 miles and the actual is 12 miles, so the error was 15.2 - 12 which equals 3.2 miles.

The error is 3.2 miles for every 12 miles I believe the percentage error is

error/actual x 100

3.2/12 x 100 = 26.667 %  

rounding off to the nearest whole percent is 27%        Final Answer
