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:
17.15 m/s
Explanation:
This is a case of free fall, so we can use the next equation:
where
is the final velocity
is the initial velocity (0 in this case)
is the acceleration of gravity 
and 
is the height at wich the ballon was pitched.
So we have:
The final velocity, the velocity of the ballon when it hits the ground is 17.15m/s.
Answer: Supply of cocoa will fall; Demand rises; Price increases.
Explanation:
A drought is when there is little or no rainfall in a particular area. When countries that are producing cocoa experience a drought, this will lead to a reduction in the supply of cocoa as there will be lesser cocoa available for farmers to supply.
Then, due to the new study which is released demonstrating the health benefits of cocoa, this will lead to an increase in the demand for cocoa. The demand will rise and since there's increase in demand and reduction in supply, the price will rise.
