Answer:
IRR= 21.86%
Explanation:
Giving the following information:
Initial investment (PV)= $10,000
Cash flows (PMT)= $4,000 per year
Number or years (n)= 4
<u>It is extremely difficult to calculate the IRR using the formula. We will use the financial calculator.</u>
Function: CMPD
n= 4
I%= SOLVE = 21.86%
PV= 10,000
PMT= -4,000
IRR= 21.86%
Answer: (i) $20 per model
(ii) $27 per model
(iii) Ginny has a comparative advantage in building models.
Explanation:
A country or a firm has a comparative advantage in producing a commodity if the opportunity cost of producing that commodity in terms of other commodities is lower than the other country or firm.
Opportunity cost is the benefit that is foregone for an individual by choosing one alternative over other alternatives available to him.
If the opportunity cost is lower for an individual then this will benefit him whereas if the opportunity cost is higher then this will not benefit the individuals.
Therefore,
Ginny's Opportunity cost of producing one model = 
= $20 per model
Eric’s opportunity cost of building models = $20 + 35% of $20
= $20 + $7
= $27 per model
Hence, Ginny has a comparative advantage in building models because Ginny's opportunity cost of building model is lower than Eric's opportunity cost.

Answer: I am right, the increased demand represents a rightward shift of the aggregate demand curve.
Explanation:
The increase in aggregate demand by foreigners occurred as a result of a fall in the value of the US dollars and aggreagrate price level stayed the same. Therefore, the change in aggregate demand didn't occur as a result of a change in price.
If agregrate demand changed as a result of a change in the aggregate price levels, there would be a change in quantity demanded and a movement along the demand curve.
It's only a change in price that result results in a movement along the aggregate demand curve.
Other factors that leads to a change in demand either shifts the aggregate demand curve to the left or to the right.
Therefore, an increase in aggregate demand as a result of the fall in value of US dollars causes the aggregate demand curve to shift to the right.
The shift in the aggregate demand curve to the right shows that demand has increased but aggregate price hasn't changed.
