Question

A local car wash is open 12 hours a day. It uses 1/4 of a container of wax for each car . The car wash waxes an average of 10 cars per hour. How many containers of wax does the car wash use in one day?

Answer 1

The car wash needs 30 containers of wax per day. If the car wash washes 10 cars per hour, with 12 hours working, that is 120 cars in total. Each car uses 1/4 a bucket, so you just divide 120 by 4. 120/4=30. Your answer is 30
