1- The following table shows the number of dishes that can be prepared at a restaurant, depending on the number of cooks in the kitchen.

Number of Cooks	Number of Dishes Prepared	Marginal Product of Labor	Marginal Revenue of Labor
0	0	(1)	(6)
1	10	(2)	(7)
2	18	(3)	(8)
3	23	(4)	(9)
4	27	(5)	(10)

1. (1-5)Calculate the Marginal Product of Labor for each row
2. (6-10) Suppose each dish sells for$15.Calculate the Marginal Revenue Product of Labor.
3. Do you observe diminishing marginal returns? Explain.

2- The following table gives the demand for labor at a grocery store.

Wage ($)	Number of Labor Hours	Wage Elasticity of Demand
$10	2	(1)
$8	3	(2)
$6	4	(3)
$4	5	(4)
$2	6	(5)

1. (1-5) Calculate the wage elasticity of demand at points along the demand curve. Indicate whether the elasticity is elastic, inelastic, or unitary elastic.
2. Draw the demand for labor curve.
3. As you slide down the along the demand curve, does the demand curve become more or less elastic?

3- The following table includes the supply of labor and Marginal Revenue Product of Labor information for a candy shop.

Wage ($)	Supply of Labor Hours	MRPL	Total Labor Cost	Marginal Expense of Labor
4	18	29	(1)	(6)
5	19	27	(2)	(7)
6	20	25	(3)	(8)
7	21	23	(4)	(9)
8	22	21	(5)	(10)

1. (1-10) Calculate the total labor cost and the marginal expense of labor for each level of employment?

2. If the candy shop is maximizing profits, how many hours of labor will be hired? What will be the offered wage?
