A college student is looking for a data plan for her cell phone. She has found an option that offers a 2 gigabyte monthly allowance for data. The monthly cost of this plan can be represented by function C, defined by: C(x) = 30x + 5, where x is the gigabyte of data used over the monthly allowance. Her budget is $50 a month. To 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 for x makes this equation true? Group of answer choices
A. x = 2
B. x = 3.5
C. x = 1.5
