The total amount Vincent will make each year from the apartments will be $127,250.
Computation:
Given,
First, total rental income from all the 15 apartments for the entire year is computed as follows:
[tex]\begin{aligned}\text{Income from Rental Apartments}&=\text{Rent per month}\times\text{Total Units}\times12\\&=\$833\times15\times12\\&=\$149,940\end{aligned}[/tex]
Now, the net income is computed based upon the total income and total expense:
[tex]\begin{aligned}\text{Net Income}&=\text{Income from Rental Apartments}-\text{Taxes and Building Upkeep}\\&=\$149,940-\$22,690\\&=\$127,250\end{aligned}[/tex]
Therefore, option a. $127,250 is correct for the net income of Vincent from the rental property after paying off the taxes and charges for upkeeping the building every year.
