Answer:
c. 5
Explanation:
L Q MPL (ΔinQ/ΔinL) VMPL
4 52
5 60 8 80
6 66 6 60
7 70 4 40
8 72 2 20
Note: Labour hired per day = L, Total product = Q, Marginal Product of labor=MPL, VMPL =Price*MPL
A firm will maximize the profit by increasing the number of labor as long as VMPL is higher than or equal to the wage rate. In this case, we observe that VMPL ($80)>wage rate ($75) for L=5 but VMPL ($60)<wage rate ($75) for L=6. So, the optimal number of labor to be hired is 5.
Answer:
The maximum investment is $6,360.111
Explanation:
Giving the following information:
The placement of a new surface would reduce the annual maintenance cost to $500 per year for the first 3 years and to $1000 per year for the next 7 years. After 10 years the annual maintenance would again be $2500.
We need to find the net present value. The maximum initial investment will be the amount that makes the NPV cero.
NPV=∑[Cf/(1+i)^n]
Cf= cash flow
<u>For example:</u>
Year 1= 500/1.05= 476.19
Year 3= 500/1.05^3= 431.92
Year 5= 1,000/1.05^5= 783.53
NPV= 6,360.111
The maximum investment is $6,360.111
Answer:
company B's cost of equity is 14.0375% - 8.975% = 5.0625% higher than company A's cost of equity
Explanation:
cost of equity = risk free rate + (beta x market premium)
risk free rate = 4.25%
market premium = market return - risk free rate = 11% - 4.25% = 6.75%
Company A's cost of equity = 4.25% + (0.7 x 6.75%) = 8.975%
Company B's cost of equity = 4.25% x (1.45 x 6.75%) = 14.0375%
this means that company B's cost of equity is 14.0375% - 8.975% = 5.0625% higher than company A's cost of equity.
