Luis rents a paddleboat to use at West Park for the day. He has to pay a deposit and an hourly fee. Using information from the graph, enter the values that complete the equation for this situation.

Answer 1

Slope = (40−30)/(4−2) = 10/2 = 5, so the hourly fee is $5/hour.
Use (2,30): 30 = 5(2) + b → b = 20, so the deposit is $20.

Equation: C(h) = 5h + 20.
