Use the five-step thinking plan to you solve this problem. four boys share a large pizza that costs $9.00. how much will each boy owe?

Step 1:
 We define the variables:
 x = cost of pizza
 y = each child's debt
 n = number of children
 Step 2:
 We have the following equation:
 y = x / n
 Step 3:
 We define the value of each variable:
 x = $ 9.00
 n = 4
 y =?
 Step 4:
 We substitute the values:
 y = (9.00) / 4
 Step 5:
 We find the solution dividing both values:
 y = 2.25 $
 
 each boy will owe:
 y = 2.25 $
