Amount of rent charged by Natalie per house = $1490
Number of houses Natalie has = 3
So
Amount of rent Natalie gets from 3 houses per month = (3 * 1490) dollars
= 4470 dollars
Amount of money Natalie gets from 3 house per year = (12 * 4470) dollars
= 53640 dollars
Amount of money Natalie
pays for maintenance per house per year = $5850
Then
Amount of money Natalie
pays for maintenance of 3 houses per year = (3 5850) dollars
= 17550 dollars
Then
Amount of money earned by Natalie in 1 year = (53640 - 17550) dollars]
= 36090 dollars
Amount of money earned by Natalie in 7 years = (7 36090) dollars
= 252630 dollars.
