A store received 20 pallets of paper products to stock. Half the pallets were paper towels, a quarter were tissues, and a fifth were paper plates. The rest were paper cups. How many pallets of paper cups did the store receive?
Thoughts? Step-by-step reasoning:
The store received 20 / 2 = 10 pallets of paper towels. They received 20 / 4 = 5 pallets of tissues. They received 20 / 5 = 4 pallets of paper plates. Thus, the store received 20 - 10 - 5 - 4 = 1 pallet of paper cups.
Thus, the answer is 1.
