Answer: 15000; 3750
Explanation:
From the question,
Q = 660 – 12P
MC = 5
The consumer surplus in a perfectly competitive market will be:
P = MC
Therefore, P = 5
Q = 660 - 12P = 660 - 12(5) = 660 - 60 = 600
Consumer surplus = 1/2 × (55 - 5) (600)
= 1/2 × 50 × 600
= 15,000
For monopoly, MR = MC
Total Revenue = P × Q
Since Q= 660 - 12P
P = (660 - Q)/12
TR = P × Q
= (660 - Q)/12 × Q
= (660Q- Q²)/12 × Q
MR = (660 - 2Q)/12
MR = MC
(660 - 2Q)/12 = 5
(660 - 2Q) = 5 × 12
660 - 2Q = 60
2Q = 660 - 60
2Q = 600
Q = 600/2
Q= 300
Since P =(660 - Q)/12
= (660 - 300)/12
= 360/12
= 30
Consumer surplus = 1/2 × (55 - 30) (30)
= 1/2 × 25 × 300
= 3750
Therefore, the answer is 15000; 3750
Answer:
(B) $5,000 favorable.
Explanation:
Variable cost flexible budget variance:
budget for 6,000 units total variable cost: $180,000
We divide the total cost by the activity in that budget:
$180,000/ 6,000 = 30
Now we multiply by the actual volume:
5,000 x 30 = 150,000
Now we do flexible budget - actual cost = variance
150,000 - 145,000 = 5,000 favorable
It is favorable, as the cost where less than expected.
Answer:
D. $221072.
Explanation:
In this question, we use the future value formula which is shown in the spreadsheet.
The NPER represents the time period.
Given that,
Present value = $0
Rate of interest = 5%
NPER = 25 years
PMT = 4,632
The formula is shown below:
= -FV(Rate;NPER;PMT;PV;type)
So, after solving this, the answer would be $221,071.92
Answer:
beta of stock B = 1.33
Explanation:
the beta of treasury bills is 0
the beta of stock A = 1.46
the beta of stock B = ?
the portfolio contains equal amounts of each investment and its overall beta is 0.93
0.93 = (0 x 1/3) + (1.46 x 1/3) + (B x 1/3)
0.93 = 0 + 0.4867 + 0.333B
0.93 = 0.4867 + 0.333B
0.4433 = 0.333B
B = 0.4433 / 0.333 = 1.33
Answer:
$1,057.86
Explanation:
Payroll taxes include:
- Social security tax withholdings 6.2% (on the first $132,900 of wages paid) = 6.2% x $8,338 = $516.96
- Medicare tax withholding 1.45% = 1.45% x $8,338 = $120.90
- Federal unemployment taxes (FUTA) 0.6% = $7,000 x 0.6% = $42
- State unemployment taxes (SUTA) 5.4% = $7,000 x 5.4% = $378
total payroll taxes = $1,057.86
