Question

The membership fee for joining a camp association is $45 a local campground charges members of the camping association $35 per night for a campsite and nonmembers $40 per night for a campsite after how many nights of camping is the total cost for members including the membership fee, the same as the total cost for nonmembers

Answer 1

45 + 35x = 40x
45 = 40x - 35x
45 = 5x
45/5 = x
9 = x <=== they are the same cost at 9 nights
