Answer:
(i) 900 CDs
(ii) Greater than; $1,650
Explanation:
(1) Break-event point will be when the contribution margin from total sales is equal to fixed costs,
Contribution Margin = Selling price - variable cost
= $(21.5 - 9.5)
= $12
Contribution Margin *Number of CDs sold = $10,800
Break-even point for Studio A = 10,800 ÷ 12
= 900 CDs
(2) Studio A would be more profitable when the extra profit earned from per unit sale of CD exceeds the extra fixed cost given in Studio A.
Extra Contribution margin in Studio A = $(12-10)
= $2
Extra Fixed cost in Studio A = $(10,800 - 7,500)
= $3,300
Studio A should be chosen if sales is greater than (3300/2) = $1,650.
Answer:
Option (D) is correct.
Explanation:
Value of Yahoo:
= Shares × Price
= 110 shares × $20
= $2,200
Value of General Motors(GM):
= Shares × Price
= 210 shares × $20
= $4,200
Value of Standard and Poorʹs Index Fund (SPY):
= Shares × Price
= 70 shares × $130
= $9,100
Total value = Value of Yahoo + Value of GM + Value of SPY
= $2,200 + $4,200 + $9,100
= $15,500
Therefore,
Portfolio weight of YHOO:
= Value of YAHOO ÷ Total value
= $2,200 ÷ $15,500
= 0.1419 or 14.19%
Portfolio weight of GM:
= Value of GM ÷ Total value
= $4,200 ÷ $15,500
= 0.2709 or 27.09%
Therefore, the portfolio weight of YHOO and GM are 14.2% (approx) and 27.1% (approx), respectively.

As seen in the chart B has the comparative advantage in coal because 1/3 > 1/5 It means they are better at producing coal than the U.S.Have in mind examples like:
U.S.
1 barrel of oil = 4 hrs
1 ton of coal = 5 hrs
B
1 barrel of oil = 7 hrs
1 ton of coal = 3 hrs
After seeing this we can say that the country which has more availability has a comparative advantage over other countries.
Hope this helps
