If a fishing boat owner brings 10,000 fish to market and the market price is $7 per fish, she will have $70,000 in total revenue. If the average variable cost of 10,000 fish is $4 and the fixed cost of the boat is $20,000, what is her profit?

Question 13 options:

A) $1.

B) $3.

C) $3,000.

D) $10,000.

The total cost is the sum of the fixed cost and the variable cost per unit multiplied by the number of units:

Total cost = $20,000 + ($4 * 10,000) = $20,000 + $40,000 = $60,000

Profit is calculated by subtracting the total cost from the total revenue:
Profit = $70,000 - $60,000 = $10,000

Therefore, her profit is $10,000.

The correct answer is D) $10,000.
