Question: There are 84 people waiting in line to ride a roller coaster at an amusement park.  The roller coaster has 7 cars, and each car seats 2 people.  How many times will the ride operator have to run the roller coaster to give everyone in line a turn?
Answer: Each run will hold 7 * 2 = <<7*2=14>>14 people.
The ride will have to run 84 / 14 = <<84/14=6>>6 times.
