Question 1095037: a car wash offers yearly membership for the price of $18. Each membership entitles the customer to a discount of 25% off the regular price of each service. If a customer spends a total of $261 in a year at the car wash, including the cost of a membership, how much would that customer have paid for the same services without the membership? Answer by ikleyn(52920) (Show Source):
Let x = the regular price for one service.
Then the number of services = N = .
The cost for the same number of services without the membership discount is
Cost = x*N = = = 324 dollars.
