What is the gross income from an apartment building with 5 units yielding different monthly and weekly rents?

To determine the gross income from an apartment building with multiple units, you'll need to calculate the total income derived from all units over a specific period, typically on an annual basis.

If the correct answer is $20,100, it implies that the combined rental income from all five units over the year totals this figure. To arrive at the gross income, one would generally sum the monthly rents of each unit multiplied by 12, which accounts for the income generated over a year. In some cases, weekly rents can also be converted to a monthly basis by multiplying weekly rents by the average number of weeks in a month (approximately 4.33 weeks).

The careful aggregation of all rental incomes, including any possible additional fees or adjustments, leads to the value of $20,100, representing the financial output of the apartment building. This calculation requires careful attention to detail in accounting for how each unit contributes to the overall income.

The other suggested values would reflect inaccuracies in either calculations or the assumption regarding the number of units or their respective rents. Hence, $20,100 stands as the accurate representation of the gross income from the apartment complex in question.
