Imagine you join a gym that has a one-time $20 registration fee and then costs $10 every time you use the gym. . What is the y-intercept, and what does it mean in context of the problem?

Answer 1

C(g) = 20 + 10g

the y intercept = $20 = the registration fee, the Cost without using the gym one time

(g, C(g) = (0, C(0)), = (0, 20) = the y intercept
