Answer:
Option B.
Step-by-step explanation:
Helen bought a four-unit apartment building for $561,000. The property lost value at a rate of 4.1% per year.

where, a is initial value, r is decreasing rate and t is time in years.
The value of building after 8 years is

Diminishing value = Initial value - Value after 8 years
= 561,000 - 401,339
= 159,661
Helen rented out each unit for $530 per month, and paid $11,200 per year in upkeep costs.
Total rent of 4 units for 8 years = 
Total upkeep cost for 8 years = 
Total earning = Total rent of 4 units for 8 years - Total upkeep cost for 8 years
= 203520 - 89600
= 113920
Profit = Total earning - Diminishing value
= 113920 - 159661
= -45,741
Round the answer to the nearest hundred dollars.
Profit = -45,700
Negative sign represent the loss. It means Helen’s total loss is $45,700.
Therefore, the correct option is B.
