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 $
Answer:
each boy will owe:
y = 2.25 $
