Answer:

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
