Question

It requires approximately 9 mL of polyethylene to create 24 plastic bags. What is the rate of polyethylene used per plastic bag?

Answer 1

0.375mL/polyethylene

Explanation:

Total number of plastic bags = 24 plastic bags

amount of polyethylene created = 9mL

This means that;

24 plastic bags = 9mL of polyethylene

1 plastic bags = x

Cross multiply

24 * x = 9 * 1

24x = 9

x = 9/24

x = 0.375mL/polyethylene

Hence the rate of polyethylene used per plastic bag is 0.375mL/polyethylene
