Use the table to answer the following questions
Output | Total Revenue | Total Cost |
0 | 0 | 30 |
1 | 40 | 55 |
2 | 80 | 98 |
3 | 120 | 125 |
4 | 160 | 152 |
5 | 200 | 180 |
a) What is the price of the product? b) What is the marginal revenue from the fourth unit output? c) What is the profit, when firm produce 5 units?
In order to determine the price, we shall calculate marginal revenue.
Output | total revenue | marginal revenue |
0 | 0 | - |
1 | 40 | 40 |
2 | 80 | 40 |
3 | 120 | 40 |
4 | 160 | 40 |
5 | 200 | 40 |
Marginal revenue is the revenue earned from the sale of an additional unit of output . It is calculated as-
Marginal revenue of nth unit= Total revenue of nth unit- Total revenue of( n-1)th unit
a)From the above table we can see that the Marginal revenue earned from each additional unit of output is same and constant. It means that the price of the product is same and constant at all levels of output. When Marginal revenue (MR) is same and constant at all levels of output, Price is equal to marginal revenue (MR). This is because when price is same at every level of output, the Marginal revenue earned from the sale of an additional unit of output is same as that of price and is constant. Hence, P=MR and the price of the product is 40.
b) Marginal revenue is the revenue earned from the sale of an additional unit of output. It is calculated as-
Marginal revenue of nth unit= Total revenue of nth unit - Total revenue of( n-1)th unit
For 4th unit of output-
Marginal revenue of 4th unit= total revenue of 4 units- total revenue of 3 units
Marginal revenue of 4th unit= 160-120= 40
For 5th unit of output-
Marginal revenue of 5th unit of output= total revenue of 5 units- total revenue of 4 units
Marginal revenue of 5th unit= 200-160= 40
Hence, we can see that marginal revenue from the fourth unit of output is 40.
c) When the firm produces 5 units of output, total cost of producing 5 units is 180 and total revenue earned from the sale of 5 units is 200. As total revenue>total cost, firm is earning Profit.
Profit= total revenue- total cost
Profit= 200-180
profit= 20
Hence, when the firm produces 5 units of output, profit is 20.
