Question

The rent charged for the different sized office spaces in an office building is as follow:

600 sqft= $1250
900 sq ft=$1850

Rent includes not only cost per square foot (same size) but also includes a processing fee.
How much are the two costs?

Answer 1

Explanation:

600 ft^2 * (x dollars)/ft^2 + fee = 1250

900 ft^2 * (x dollars)/ft^2 + fee = 1850

Subtract first equation from second equation:

300x = 600

x = 2 dollars per sq ft

600x + fee = 1250

Fee = $50

Cost = $2/sq ft

Processing fee = $50
