Fitness for Families offers two exercise class options. The first option costs $50 plus $2 per class. The second option has no initial fee, but each class is $6. You want to compare the 2 options to see which option is the better choice. Part A. Should you use equations or inequalities to model this story? Write one complete sentence explaining how you know. Part B. Write a system of equations or inequalities to model this story. Part C. If you plan to attend 15 exercise classes, which option is the better choice? Show your work or explain how you found your answer.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
