Anna wants to rent movies from either Service A or Service B. Service A charges $37.92 as a subscription fee with a charge of $2
.18 per movie. Service B charges $33.25 as a subscription fee plus $3.55 per movie. Service B is running a special offer where the first movie is free. Given that Anna always rents at least 1 movie in a given subscription period, how many movies would she have to rent for the average cost per movie to be equal at Service A or Service B?
There are nine boxes in each pack. Garth bought 2 packs, all together containing 18 boxes. So 18÷2=9. Rico bought 4 packs, so 36 boxes divided by 4 equals 9. And so on. Your answer is 9 boxes = 1 pack.
