Question

Michelle wants to order cookies. It is $6 for 4 pcs, how much would it cost for 20 pcs?

Answer 1

$30

Explanation:

4pcs = $6

20pcs = x

Cross multiplying, we have

x = (20pcs * $6)/4pcs

= $120/4 = $30

Answer 2

6 divided by 4 is 1.5.

1.5 times 20 is 30

it would cost michelle $30 to buy 20 pieces of cookies
