Local chain of sandwich shops sells sandwiches in a competitive market at $5.39 each. The hourly production function is:
Q = 136L - L2
The marginal product of labor function is:
MPL = 136 - 2L
If the competitive hourly wage is $14.68
a) how many employees do they hire?
b) what are the total hourly labor costs for the firm?
c) what is the total output of the firm?
d) what is the total revenue of the firm?

3 | Q= 136L-L2 | ||||||
4 | MPL = 136-2L | ||||||
5 | |||||||
6 | a) | ||||||
7 | |||||||
8 | The maximum output will be where the marginal product of labor function is zero i.e. | ||||||
9 | 136-2L = 0 | ||||||
10 | |||||||
11 | Solving the above euation | ||||||
12 | L= | =136/2 | =136/2 | ||||
13 | |||||||
14 | Thus number of enpmloyees to be hired is | =D12 | |||||
15 | |||||||
16 | b) | ||||||
17 | |||||||
18 | Hourly wage | 14.68 | |||||
19 | Number of Labors | =D14 | |||||
20 | Total hourly labor costs | =D18*D19 | =D18*D19 | ||||
21 | |||||||
22 | Hence Total hourly labor costs | =D20 | |||||
23 | |||||||
24 | c) | ||||||
25 | |||||||
26 | Total output of the firm can be calculated using hourly production function. | ||||||
27 | Q= 136L-L2 | ||||||
28 | Q= 136*68-682 | ||||||
29 | |||||||
30 | Q= | =136*68-68^2 | =136*68-68^2 | ||||
31 | |||||||
32 | Hence total output of the firm is | =D30 | |||||
33 | |||||||
34 | d) | ||||||
35 | |||||||
36 | Price per units | 5.39 | |||||
37 | Number of units produced | =D32 | |||||
38 | Total Revenue | =D36*D37 | =D36*D37 | ||||
39 | |||||||
40 | Hence total revenue of the firm is | =D38 | |||||
