Trevor pays $125 in fees each semester plus $650 per college course. last semester trevor paid $2,725. which function represents trevor’s bill? a. f(x) = 125x + 650 b. f(x) = 650x + 125 c. f(x) = 775x d. f(x) = 525x

The correct answer is Choice B.

This is an example of an equation in slope-intercept form, y = mx + b.

The slope, m, is the amount of increase each course, or 650.
The y-intercept, b, is the starting fees that are paid.

Put them together and you have: y = 650x + 125 of Choice B.
