Your parents have decided that it is time for you to have some responsibility by paying for your own cell phone bill. You have a job, but you remain on a strict budget. For your cell phone, you have planned to spend no more than $25 per month. You need to determine which company, My Mobile or Cell For You, is the best for you. 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?
