Question: Marsha works as a delivery driver for Amazon. She has to drive 10 miles to deliver her first package, 28 miles to deliver her second package, and half that long to deliver her third package. If she gets paid $104 for the day, how many dollars does she get paid per mile?
Answer:
First find how far Marsha drives to deliver the third package: 28 miles / 2 = 14 miles. Then find how many miles she drives total by adding the miles for the three legs of her journey: 14 miles + 28 miles + 10 miles = 52 miles. Then divide her total pay by the number of miles she drives to find her pay per mile: $104 / 52 miles = $2 / mile. The answer is 2.
