A gym charges a one-time registration fee and then $25 per month. After 6 months, a customer has paid $205 in total. Write a linear model for total cost (C) in terms of months (m), and find the registration fee.

C = 25m + 50; registration fee = $50

C = 30m + 25; registration fee = $25

C = 25m + 30; registration fee = $30

C = 20m + 55; registration fee = $55

A worker paints fences at a constant rate. After painting 3 fences, he has worked for 4 hours. After 9 fences, he has worked 10 hours. Create a linear model to represent time (t) as a function of fences painted (f). How long will it take to paint 15 fences?

t = f + 2; 17 hours

t = f + 1; 16 hours

t = f + 3; 18 hours

t = f + 0.5; 15.5 hours

A repair technician charges $80 for the first hour, which includes a $20 travel fee. Each additional hour costs $60. What is the linear model for total cost (C) after h hours of work (where h ≥ 1)?

C = 80h + 20

C = 60(h – 1) + 80

C = 60h + 20

C = 60h + 80

P = –8s + 48;

0 passengers

P = 8s – 40;

16 passengers

P = 40 – 8s;
