A campus courtyard is in the shape of a rectangle and consists of grass surrounded by a concrete path. The dimensions of the entire courtyard are 25 ft. by 20 ft. The concrete path is 3 feet wide all the way around. The school decides to replace the
grassy area. A landscaping company charges $.20 per square foot for grass and $.60 per square foot to install it.
Approximately how much would the school save if the math club volunteered to install it instead of having the landscape
company install it?
