given the building layout, what portion of the shared $7200 maintenance costs should store b contribute?\nstore a 2500 ft²\nstore b 625 ft²\nstore c 1250 ft²\nstore d 1250 ft²\napportioned cost = $?
Answer
Explanation:
Step1: Calculate total area
$2500 + 625+1250 + 1250=5625$ (square - feet)
Step2: Calculate proportion of Store B
The proportion of Store B's area to the total area is $\frac{625}{5625}=\frac{1}{9}$
Step3: Calculate Store B's cost
Store B's contribution to the maintenance cost is $\frac{1}{9}\times7200 = 800$
Answer:
$800$
