Camp Far From Home allows campers to take the horses out for joy rides through the woods for an additional fee. The camp typically charges campers $20 per ride. However, there are some campers who like to ride so often, the camp recommends they join the riding club. The membership fee is $75, but members are only charged $7.50 per ride. For how many rides would both options be the same price? What wound the cost be for that number of rides?
