Answer:
MRPL= $200 = wage rate when there are 5 workers
and MRPL = $1,200 = wage rate when there are 2 workers.
Explanation:
The computation of unionized is shown below:-
Marginal revenue product of labor = Marginal product × Price per unit
Workers Total Production Marginal Product MRPL
(per day)
a b b × $8
0 0
1 200 200 $1,600
2 350 150 $1,200
(350 - 200)
3 450 100 $800
(450 - 350)
4 500 50 $40
(500 - 450)
5 525 25 $200
(525 - 500)
6 510 -15 -$120
(510 - 525)
From the above table MRPL = $200 = wage rate when there are 5 workers
and MRPL = $1,200 = wage rate when there are 2 workers.
Answer: Option (d) is correct.
Explanation:
Amount paid for candy = $1,500
Items received = 8,500 pieces of candy
Group 1 = 2,500 pieces
Selling price = $0.15 each
sale value = pieces sold × Selling price
= 2,500 × $0.15 each
= $375
Group 2 = 5,500 pieces
Selling price = $0.36 each
sale value = pieces sold × Selling price
= 5,500 × $0.36 each
= $1,980
Group 3 = 500 pieces
Selling price = $0.72 each
sale value = pieces sold × Selling price
= 500 × $0.72 each
= $360
Total sale value = $375 + $1,980 + $360
= $2,715


= 72.92%
Proportion of cost for Group 2 = cost × Percentage of sale in Group 2
= $1,500 × 72.92%
= $1,093.8


= $0.1988
= $0.20(approx)

Answer:
Explanation:
Expected return of the portfolio is weighted average of the return of the components.
E(R) = w1 * R1 + w2 * R2
E(R) = 65% * 18% + 35% * 6%
E(R) = 11.70% + 2.10%
Expected Return, E(R) = 13.80%
Standard deviation of portfolio is mathematically represented as:

where
w1 = the proportion of the portfolio invested in Asset 1
w2 = the proportion of the portfolio invested in Asset 2
σ1 = Asset 1 standard deviation of return
σ2 = Asset 2 standard deviation of return
For risk free money market fund, standard deviation = 0 and its correlation with risky portfolio = 0

Standard deviation = 19.50%
