Hence:

Answer:
5: ? = 52
9: x = 10
Step-by-step explanation:
For this case we find the expression that represents the cost of each printing press.
x: Be the variable that represents the number of programs to print
So:
Cost 1: Janet’s Print Shop

Cost 2: The Printing Press

If we want to find the number of programs for which the costs are the same, then we equate both equations:

Thus, for 150 programs the cost is the same.
Answer:
For 150 programs the cost is the same.
