Final answer:
The owner forecasts revenues of $192,000 a year and has variable costs of $58,000, rental costs of $38,000, and depreciation costs of $18,000. To find the owner's profit, we subtract the total costs from the revenues to get $78,000.
Step-by-step explanation:
The owner of the bicycle repair shop forecasts revenues of $192,000 a year. The variable costs are $58,000, rental costs for the shop are $38,000 a year, and depreciation on the repair tools is $18,000. To find the owner's profit, we need to subtract the total costs from the revenues:
Profit = Revenues - Total Costs
Profit = $192,000 - ($58,000 + $38,000 + $18,000)
Profit = $192,000 - $114,000
Profit = $78,000
Therefore, the owner's profit is $78,000 (option c).
