Answer:
1.15
Explanation:
If investment is made in equal proportions, it means that;
weight in risk free ; wRF = 33.33% or 0.3333
Let the stocks be A and B
weight in stock A ; wA = 33.33% or 0.3333
weight in stock B; wB = 33.33% or 0.3333
Beta of A; bA = 1.85
Let the beta of the other stock be represented by "bB"
Beta of risk free; bRF = 0
Beta of portfolio = 1 since it is mentioned that "the total portfolio is equally as risky as the market "
The weight of portfolio is equal to the sum of the weighted average beta of the three assets. The formula is as follows;
wP = wAbA + wBbB + wRF bRF
1 = (0.3333 * 1.85) + (0.3333*bB) + (0.3333 *0)
1 = 0.6166 +0.3333bB + 0
1 - 0.6166 = 0.3333bB
0.3834 = 0.3333bB
Next, divide both sides by 0.3333 to solve for bB;
bB = 0.3834/0.3333
w=bB = 1.15
Therefore, the beta for the other stock would be 1.15
Answer:
Cost of 1 hamburger and 1 shake is $1.89
Explanation:
Assume:
Cost of hamburgers = h
Cost of milkshakes = m
For Jack
2h + 3m = $4.21.......Eq1
For Jill
3h + 2m = $5.24.........Eq2
Eq1 + Eq2
5h + 5m = 9.45
divide by 5
h + m = $1.89
So,
Cost of 1 hamburger and 1 shake is $1.89
Answer:
B) change in average total costs divided by the change in output.
Explanation:
Marginal cost is the extra cost incurred for the production of an additional unit of output after breakeven. At the breakeven point, fixed costs have been absorbed. Any additional production will incur variable costs . Marginal costs will, therefore, comprise direct labor, direct material, and a small proportion of fixed costs, such as administration and selling costs.
The calculate marginal cost, divide the total change in costs by the change in the product output. i.e.
Marginal costs = change in cost / change in output.
Marginal cost is compared with marginal revenue when deciding whether to increase production or not.
