The Ariana's accounting profit for the year was $6,000
Explanation:
Accounting Profit : The accounting profit is that profit which records the difference of total revenues and total direct cost.
Where,
Total revenues includes sales revenues
And total cost includes monetary cost, etc.
So,
Accounting profit = Total revenues - Total cost
where
Total revenues = 2,000 × $2.5 + 4,000 ×$2.5 = $15,000
Monetary cost = $9,000
So,
Accounting profit = $15000 - $9000 = $6,000
Hence, the Ariana's accounting profit for the year was $6,000
