Question

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.

Answer 1

Explanation:

Answer:

4 bags of chips

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
