Question

A local car wash is inviting customers to join the Concierge Club, in which you can have your car washed as many times as you wish for a fixed monthly fee. Amy creates the graph below to compare the cost per wash versus the cost for the Concierge Club. Which conclusion is supported by the graph?

Answer 1

Answer is Choice D, that the pay per wash is 5.00 per wash.

Explanation:

Since that is the only point marked (6,30) you divide the total cost (30) by (6) and you get 5.00.

Answer 2

I'm pretty sure the answer is D. You can see that 6 washes is 30 dollars so that would make each wash $5 and all other answers can be proven wrong or not proven to be true.
