Question

For a party, 50 dinner rolls are needed. Dinner rolls are sold in packages of 12 . What is the minimum number of packages that should be bought for the party?

Accepted Answer

The correct answer is 5 . Let p represent the number of packages of dinner rolls that should be bought for the party. It's given that dinner rolls are sold in packages of 12 . Therefore, 12 p represents the number of dinner rolls that should be bought for the party. It's also given that 50 dinner rolls are needed; therefore, 12 p &#8805; 50 . Dividing both sides of this inequality by 12 yields p &#8805; 50 12 , or approximately p &#8805; 4.17 . Since the number of packages of dinner rolls must be a whole number, the minimum number of packages that should be bought for the party is 5 .
