[Question]Laura’s House is a 20-mile round trip from her school. The supermarket is 10 miles farther away from the school. If Laura drives to school every morning and two afternoons a week drives to the supermarket. How many miles does Laura driver per week?
[Answer]7 days a week Laura drives 20 miles to school, so Laura drives 7 x 20 = 140 miles to school in one week. The supermarket is 10 miles farther away than the school. Therefore the supermarket is 10 + 10 = 20 miles away from Laura’s house. Laura drives 20 miles each way to and from the supermarket. Each trip is 20 x 2 = 40 miles. Laura drives 40 miles twice a week to visit the supermarket. Therefore she drives 40 x 2 = 80 miles in total a week to and from the supermarket. In total Laura drives 140 + 80 = 220 miles each week. The answer is 220.

A: He has 2,000 pounds of fish because 10 x 200 = 2,000. He has enough for 80 customers because 2,000 / 25 = 80. 20 customers go home without any fish because 100 - 80 = 20. The answer is 20.
