The My Mobile "Pay-As-You-Go" monthly plan consists of a charge of $19.99 for unlimited calling minutes and two cents for each text message. The Cell For You "Pay-Per-Use" plan consists of a charge of $15.99 for unlimited calling and 10
cents for each text message.
Based on the information above, which plan is the best deal?
a. To solve, create a system of linear equations for the two plans. Assume y equals total cost and x equals the number of
text messages (price of the plan plus the price per text).
b. Graph the two equations on a coordinate plane and find the point of intersection. What does the point of intersection
represent in this problem?
c. Which plan would you choose? Why?
