Suppose the total cost, C, of renting a car is $25 per day plus an initial fee of $100. Which equation best describes this relationship if d represents the number of days the car is rented?

• C = 100d - 25

• C = 100d + 25

• C = 25d - 100

• C = 25d + 100

Which equation best represents the graph shown above?

• y = 2 + 2/3x

• y = 2 - 2/3x

• y = 3 + 3/2x

• y = 3 - 3/2x

Carter sells sports videos to local businesses in his area. His daily wage, W, is based on the number of hours he works, H, at the minimum wage of $7.25 per hour, plus $10 to cover gas and lunch expenses. Which equation best describes this relationship?

• W = 10H +7.25

• W = 7.25H +10

• W = 10H + 7.25H

• W = 7.25H

The temperature in degrees Fahrenheit F is the sum of 9/5 the temperature in degrees Celsius C and the constant 32. Which equation best represents this relationship?

• F = 9/5C + 32

• F = 9/5(C + 32)

• F = 9/5 + C + 32

• F = 9/5(C - 32)
