Final answer:
The total revenue is $300, profit is $75, cost per unit is $15, and the total cost is $225.
Step-by-step explanation:
a. Total revenues in this example will be a quantity of 15 units multiplied by the price of $20/unit, which equals $300.
b. Profit is calculated by subtracting the total cost from the total revenue. In this case, the total cost is $15 per unit multiplied by 15 units, which equals $225. Therefore, the profit is $300 - $225 = $75.
c. The cost per unit is given as $15.
d. Total cost is calculated by multiplying the cost per unit by the number of units. In this case, the total cost is $15 multiplied by 15 units, which equals $225.
