Kimberly was looking for data plans for her cell phone when she found a third option, which also offers a 2 gigabyte monthly allowance for data. Her budget is $50 a month. To find out how many gigabytes of data she could use with the function C(x) = 30x + 5 if she chose this plan, she writes C(x) = 50 and solves for x. What value of (x) makes this equation true?
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
