The area of a campground is 1,400 square meters. A tent requires 8 square meters and an RV requires 30 square meters of space. The capacity of the campground is 120 spots, including both tents and RVs. If the cost to camp in a tent is $3.00 and an RV is $9.00, how many RVs should be in the campground to maximize income. I understand you set it up as inequalities so it would be 8A + 30 B is less than or equal to 1400. and the other would be x + y is less than or equal to 120 but I don't understand how to solve it.
