Question

Scott Mason purchased a 4-unit apartment building as an investment before he retired. From the rent he collects each month, Scott pays out $600 for expenses. How much rent must he charge for each of the 4 apartments if he wants to make $500 profit each month?

Answer 1

let x= the amount of rent per apartment

4x - 600 = 500

by solving the equation we find

x = $275
