Solution:
Let the amount invested in scheme which yields 9% be x and amount invested in scheme which yields 13% be y.
x + y = 180000 --equation 1
0.09x + 0.13y = 18000 --equation 2
Balancing the equations, multiply equation 1 with 0.09 and equation 2 with 1,
0.09x + 0.09y = 16200 -equation 3
0.09x + 0.13y = 18000 --equation4
Subtracting equation 4 from 3,
-0.04y = -1800
y = 45000
Now putting value of y in equation 1,
x + 45000 = 180000
x = 135000
The amount to be invested in scheme which yields 9% = $135,000
The amount to be invested in scheme which yields 13% = $45,000
Answer:
D. 76.6 %
Explanation:
Contribution Margin Ratio = Contribution / Sales × 100
<em>First Calculate the Contribution</em>
Contribution = Sales - Variable Costs
= (60,000 units × $ 12.40) - ($110,000+$30,000+$34,000)
= $744,000 - $174,000
= $570,000
<em>Then Calculate Contribution Margin Ratio</em>
Contribution Margin Ratio = $570,000 / $744,000 × 100
= 76.61290
= 76.6 % ( 1 decimal)
Answer:
a) Decrease LRAS
b) Decrease LRAS
c) Increase AD
d) Increase AD
Explanation:
steel workers go on strike so less steel is produced : this will cause a decrease in the log run aggregate supply of steel in the economy
A tornado destroys factories in Louisiana.: this will cause a decrease in the log run supply of factory products and by-products in the economy
Consumer optimism increases.leads to an increase in the aggregate demand curve
The stock market rallies to 52-week highs increasing consumer wealth. this will definitely lead to an increase in the aggregate demand curve because with more money to spend the demand curve will increase
Answer:
a) the correct answer is "B"
b) the correct answer is "C"
Explanation:
a) the correct answer is "B"
relies on nominal GDP which might have increased because of price increases and not output increases. As nominal GDP accounts for the price and it is calculated at the current price level. The answer is "B".
b) the correct answer is "C"
We can ask for growth rate of real GDP which excludes price change.
Answer:
The answers are:
A) 25.23 million people
B) 70.28%
C) 4.92 million people
D) 19.50%
Explanation:
Laborland's total labor force can be calculated by adding those who are employed and those who are unemployed but were searching for a job during the last month.
- 4.6 million (part-time employed) + 15.71 million (full-time employed) + 3.2 million (looked for a job two weeks ago) + 1.72 million (looked for a job between two and four weeks ago) = 25.23 million people
Laborland's labor force participation rate can be calculated by dividing the labor force by the total population.
- (25.23 million / 35.9 million) x 100% = 70.28%
Laborland's total unemployed can be calculated by adding the number of people without a job that searched for a job during the last month.
- 3.2 million + 1.72 million = 4.92 million people
Laborland's unemployment rate can be calculated by dividing the total number of unemployed people by the total work force.
- (4.92 million / 25.23 million) x 100% = 19.50%
