Answer :
Answer:
b) 5
Explanation:
W TP MP MRP
1 100
2 190 90 900
3 270 80 800
4 340 70 700
5 400 60 600
6 450 50 500
7 490 40 400
8 520 30 300
the marginal product of n labor = (total product of n labor - the total product of p labor)/(n-p)............(n>p)
Marginal revenue product = marginal product*price
the firm employ input up to marginal revenue product equal to the wage
MRP = wage or closest lower wage
where W = 5
the firm will higher 5 workers.
Answer:
b) 5
Workers Total Production

5 400
6 450
7 490
8 520
Explanation:
Profit is maximized when marginal cost is equal to marginal revenue.
i.e MC=MR.
Workers Total Production TC MC TR MR

2 190 1200 600 1900 900
3 270 1800 600 2700 800
4 340 2400 600 3400 700

7 490 4200 600 4900 400
8 520 4800 600 5200 300
Where TC=Total Cost=worker multiply by cost per worker=$600*1=$600; etc.
MC=Marginal Cost=TC minus preceding TC=$600.
TR=Total Revenue=Total Production multiply by production price=$100*$10=$1,000, etc.
MR=Marginal Revenue=TR minus preceding TR=$1900-$1,000=$900, etc.
