Answer:
$300,000
Step-by-step explanation:
Labor cost = $11,000
Parking cost= $7,000
Parking Labor cost = $ 18,000
Parking Revenue = ?
From the question, parking labor cost is 6% of Parking revenue.
6% = Parking Labor cost/ Parking Revenue------------------------------------ (1)
Further substituting in (1) gives:
6/100 = 18,000/ Parking Revenue
Making Parking Revenue the subject of the formula, we have:
Parking Revenue = (100 x 18,000)/6
= $300,000
