Tim Horton’s sells an average of

570 cups of coffee a day The manager wants to be sure he has enough carry-out containers on hand Each carry-out container holds 4 cups of coffee If the manager expects half of all the coffee sold to be put in carry-out containers, how many will he

need for that day?

to go into carry out containers

570 ÷ 2 = 285

285 ÷ 4 cups per container = 71 R 1

71 containers are not enough 1 cup of coffee will not have a carry-out container Therefore, the manager needs to have

72 carry out containers on hand There will be 3 extra

spaces in the 72 nd container.

Answer: 72 carry out containers
