Answer :
Answer:
Optimal qauntity is 4 Units
Explanation:
Here, we have to decide quantity of production at which maximum profit can be generated. For this reason we will have to contruct a table which will help us to calculate Marginal Benefit and Marginal cost. This table is given as under:
Quantity Total benefit Marginal benefit Total Cost Marginal Cost
0 Units 0 0 0 0
1 Units 16 16 9 9
2 Units 32 16 20 11
3 Units 48 16 33 13
4 Units 64 16 48 15
5 Units 80 16 65 17
We can see that at 4 Units, marginal revenue is almost equal to marginal cost. At this level of production, we have maximum benefits generated which is:
Maximum Benefit Generated = ($16 - $9) + ($16 - $11) + ($16 - $13) + ($16 - $15) = $7 + $5 + $3 + $1 = $16 for 4 Units
We can also cross check by considering 5 units case to assess whether the benefit generated is more than 4 units case or not.
Maximum Benefit Generated (For 5 Units) = ($16 - $9) + ($16 - $11) + ($16 - $13) + ($16 - $15) + ($16 - $17) = $7 + $5 + $3 + $1 - $1 = $15 for 4 Units
As the maximum benefit generated in the case of 4 units is more because of using marginal revenue = Marginal Cost relation, hence the optimal quantity is 4 units.
