Answer 1

Krissy will earn 9 minutes of outside time if she completes 12 chores.

Step-by-step explanation:

To find out how much outside time Krissy will earn if she completes 12 chores, we can use a proportion.

First, let's set up the proportion:

4.5 minutes / 6 chores = x minutes / 12 chores

To solve for x, we can cross multiply:

4.5 * 12 = 6 * x

54 = 6x

Divide both sides by 6:

x = 9

Therefore, Krissy will earn 9 minutes of outside time if she completes 12 chores.
