Answer:
the amount of money that must be invested now is $21068.87
Explanation:
Given that:
Nominal interest = 10%
Annuity = 7000
n = 8 years
The Effective interest rate is calculated by using the formula:
Effective interest rate = 
Effective interest rate = 
Effective interest rate = 0.1045
Effective interest rate = 10.45 %
Thus ; the the amount of money that must be invested now is the present value with the annuity of $7, 000 per year for 12 years, starting eight years from now.

PV = 7000 × 6.666056912 × 0.4515171371
PV = $21068.87
Thus; the amount of money that must be invested now is $21068.87
Answer:
Increase the aggregate demand. This means, that the total demand for goods and services within a particular market will increase
Explanation:
The future expectations of an improving economy increase the aggregate demand. This means, that the total demand for goods and services within a particular market will increase as there is more trust in the market.
The rise in the income is another important factor for the aggregate demand to increase. With improving expectations the consumers will think that they income will improve and therefore their consumption levels.
Answer:
The price.
Explanation:
Elasticity is the percentage change in quantity divided by the percentage change in price.
Answer: c. small changes in economic growth rate lead to large GDP changes over time.
Explanation:
If there is even a small change in the rate at which the economy is growing, this increase will increase by even more the year afterward and then even more as time goes on. This is because the interest is being compounded overtime.
Look at the future value formula that shows compounding for instance:
Future value = Amount * (1 + rate) ^ number of periods
Assume even a change of 2% in the growth rate. In 30 years, this rate would have increased the economy by:
= 1 * ( 1 + 2%)³⁰
= 1.81
Which is a rate of:
= 1.81 - 1
= 81%
What started off as only 2% became 81% in 30 years. This is what compounding does.
Answer:
The correct answer is B. If there are 10 plants producing the total domestic consumption of a product and each plant is operating at minimum efficient scale, then each plant accounts for 10 percent of domestic consumption.
Explanation:
It is understood that the total consumption of a product is 100% of it. Therefore, as long as there are 10 plants that, producing at a minimum efficiency scale on an equal basis, cover this total consumption, the percentage of consumption that each plant produces will be 10%.
This is so because 100/10 = 10, provided that it is considered that the production is carried out equitably between each of the production plants.
