One bag of chips serves about 5 people. if you want to have a picnic with 18 people, how many whole bags of chips should you get? assume you want as little left over as possible.

4 bags of chips

Step-by-step explanation:

1 bag                     x bags

=

5 people            18 people

using cross products

1 * 18 = 5 * x

18 = 5x

divide by 5

18/5 = x

3 3/5 =x

but we can't buy 3/5 of a bag of chips so we round up

4 bags of chips
