Answer:
b. $1300 income
Explanation:
Apportionment rate = 420/1200 square feet = 35% attributable to the boutique.
Amount of income from the boutique would be all the income receipts as reduced by all the qualifying expenses relating to the business.
So, Richard's income from the boutique would be computed as under:
= $10,000 gross income - $2400 supplies expense - Depreciation attributable to boutique i.e 35% of $12,000 - utilities expenses attributable to boutique i.e 35% of 6000
= $10,000 - 2400 - 4200 - 2100
= $1300 income
