The college student who is looking for a data plan for her cell phone found a third option. The monthly cost of this option must be represented by function C, defined by C (x) = 20x + 5, where x is the gigabytes of data used. 1) Find C (0,7) and explain what it means in this situation.

2) Her budget is $50 a month. Find out how many gigabytes of data she could use if she chose this plan, she writes C(x)= 50 and solves for x. What value of x makes this equation true? Show your reasoning.
