Final answer:
The profit-maximizing quantity of output for Frank's Pasta Maker is 3 units, covering all fixed and variable operating costs. The correct answer is c. 475 units.
Step-by-step explanation:
The profit-maximizing quantity of output can be determined by finding the level of output where total revenue equals total cost. To find this quantity, we need to calculate the total revenue and total cost for each level of output and compare them.
Let's calculate the total cost for each output level:
- For 1 unit, the variable cost is $45, so the total cost is $28,500 + $45 = $28,545
- For 2 units, the variable cost is 2 * $45 = $90, so the total cost is $28,500 + $90 = $28,590
- For 3 units, the variable cost is 3 * $45 = $135, so the total cost is $28,500 + $135 = $28,635
- For 4 units, the variable cost is 4 * $45 = $180, so the total cost is $28,500 + $180 = $28,680
- For 5 units, the variable cost is 5 * $45 = $225, so the total cost is $28,500 + $225 = $28,725
Now, let's calculate the total revenue for each output level:
- For 1 unit, the total revenue is 1 * $60 = $60
- For 2 units, the total revenue is 2 * $60 = $120
- For 3 units, the total revenue is 3 * $60 = $180
- For 4 units, the total revenue is 4 * $60 = $240
- For 5 units, the total revenue is 5 * $60 = $300
Finally, let's compare the total revenue and total cost for each level of output:
- For 1 unit, the total revenue ($60) is less than the total cost ($28,545), so it is not the profit-maximizing quantity of output
- For 2 units, the total revenue ($120) is less than the total cost ($28,590), so it is not the profit-maximizing quantity of output
- For 3 units, the total revenue ($180) only just covers the total cost ($28,635), so it is the profit-maximizing quantity of output
- For 4 units, the total revenue ($240) is more than the total cost ($28,680), so it is not the profit-maximizing quantity of output
- For 5 units, the total revenue ($300) is more than the total cost ($28,725), so it is not the profit-maximizing quantity of output
Therefore, the profit-maximizing quantity of output is 3 units, so the correct answer is c. 475 units.
