Claire enrolls in a scuba diving program. The program costs include a one-time registration fee of $75 and $60 for each lesson. In addition, Claire had to purchase scuba equipment costing $275. Use this information to complete the activity. Part A: Write an equation that models the average cost per lesson (C) in terms of the number of lessons that Claire takes (x).

Part B: Use the equation you wrote to find the number of lessons Claire took if the average cost per lesson is $110.

Part C:Describe another situation that you can model using the same equation.
