Question

A school courtyard consists of a grassy green space surrounded by a gravel path. The dimensions of the entire courtyard, including the gravel path, are 30 feet by 25 feet. The gravel path is 2 feet wide. The school's SGA will be replacing the grass in the green space. The gravel path will not be replaced. A landscaping company charges $0.15 per square foot for the grass and an additional $0.50 per square foot installed. How much would be saved if the SGA installed the grass themselves instead of having the landscaping company install it?

Answer 1

$273

Explanation:

The grass area is smaller in both dimensions by 4 feet than the overall area. So the grass area is ...

26 ft by 21 ft = 546 ft^2

Since the installation cost is $0.50 per square foot, that cost is ...

($0.50/ft^2)(546 ft^2) = $273

$273 would be saved by not paying for installation.
