20. Oil Changes: You are scheduled to start your job at an oil change shop 2 hours after the shop opens. Two

hours after you start, a total of 11 cars have had their oil changed since the shop opened. Three hours later, a

total of 14 cars have had their oil changed. At what rate are cars getting their oil changed since you started

working? How many cars had their oil changed before you started work?

21. Cable Television A cable company charges $44 per month for basic service. Each premium channel costs

an additional $16 per month.

a. Write an equation that gives the total cost (in dollars) of cable each month as a function of the number

of premium channels.

b. Identify the dependent and independent variables in this situation.

c. Explain how you can use the equation from part (a) to approximate how many premium channels you

can have for $80 a month.

22. Decide whether the three points lie on the same line. Explain how you know. If the points do lie on the

same line, write an equation of the line that passes through all three points.

(3, 7), (–2, –8), (7, –19)

23. Challenge: A line passes through the points (3, 16), (–2, –14), and (h, 28). Find the value of h.

Explain your steps.
