Question

Terry is throwing a surprise party. She has invited 31 people. She is buying party favors that come in packages of 5. How many packages does Terry need to order so that she has enough for each guest to have one? ​

Answer 1

Terry needs to buy 7 packages

Explanation:

Terry has invited 31 people, meaning she needs 31 party favors

If they come in groups of five, we have to find how many packages(of 5) equal 31. Because 5 does not evenly multiply into 31, (it fits evenly inti 30) we have to add an extra package, meaning she will need 7 packages because 7×5 is 35, which is enough for each guest
