Divide.

To find out how much each person has to pay, you need to divide the total cost by the number of friends. In this case, three friends bought school supplies for $12.06. So, you need to divide $12.06 by 3.

To do this calculation, let's break down the steps:

Step 1: Divide the dollars (whole numbers)
$12 ÷ 3 = 4

Step 2: Divide the cents (decimal numbers)
0.06 ÷ 3 = 0.02

Step 3: Add the results from step 1 and step 2 together
4 + 0.02 = 4.02

Therefore, each person needs to pay $4.02 for the school supplies.
