Sarah is on a cell phone plan with her family and she has to contribute $25 per month for data. She also has to pay $.10 per text message that she sends. Let � = number of texts and � = total
cost in the month.
a. If she sends 300 text messages this month, how much does she owe her parents?
b. Create a table of 5 values showing how much Laila could possibly pay for a certain
number of texts. Include 0 texts as one of your values. (remember – you can choose ANY
x values…are there certain values that will give you friendlier y values?)
c. Create a graph using the points from your table.
d. Is the relationship between texts and total cost directly proportional? Why or why not?
