Labor (workers) | Total Product | Average Product | Marginal Product |
0 | 0 | - | - |
1 (Estella) | 7 | ||
2 | 16 | ||
3 | 21 | ||
4 | 22 | ||
5 | 18 |

Labor | Total product | Average product | Marginal product |
0 | 0 | --- | ---- |
1 | 7 | 7 | 7 |
2 | 16 | 8 | 9 |
3 | 21 | 7 | 5 |
4 | 22 | 5.5 | 1 |
5 | 18 | 3.6 | -4 |
Average product = (Total product / Labor)
Marginal product = (Change in total product / Change in labor)
(b) When there is one labor, then Estella only works and no friend is helping her.
If there is two labor, then Estella and one friend of her works.
If there is three labor, then Estella and two friends of her works.
If there is four labor, then Estella and three friends of her works.
If there is five labor, then Estella and four friends of her works.
Marginal product at 2 units of labor shows the additional glasses of lemonade can Estella produce if she has one friend help her make lemonade instead of making lemonade by herself.
Answer: 9 glasses.
--------------
(c)
Marginal product at 5 units of labor shows additional glasses of lemonade can Estella produce if she has four friends help her rather than having three friends help her.
Marginal product of labor at 5 units of labor is -4.
Hence, taking help of 4th friend will decrease the production by 4 glasses.
Answer: -4 glasses
-----------------------------
(d) Average product at 5 units of labor shows the average number of glasses of lemonade made by the Estella and her four friends.
Answer: 3.6 glasses
