A parking lot has a surface of 720 m^2.
A=720m%5E2
Each car occupies an area of 6m%5E2 and each bus occupies an area of 18m%5E2+
if number of cars occupies an area is x, and number of buses occupies an area is y, we have
6x%2B18y%3C=720...simplify
x%2B3y%3C=120

+graph%28+600%2C+600%2C+-100%2C+100%2C+-100%2C+100%2C+6x%2B18y%3C=720%29+
