Answer:
e. price elasticities of demand for apples and oranges are the same over these price ranges
Explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price.
Price elasticity = percentage change in quantity demanded / percentage change in price
Percentage change in price = (50-40) / 50 = 0.2 × 100 = 20%
Percentage change in quantity demanded of Apples = (120 - 100) / 100 = 0.2 × 100 =
20%
Percentage change in quantity demanded of oranges = (240 - 200) / 200 = 0.2 × 100 = 20%
Price elasticity of demand for oranges = 20% / 20% = 1
Price elasticity of demand for Apples = 20% / 20% = 1
When coefficient of elasticity is equal than one, elasticity of demand is unit elastic.
This implies that the elasticity of demand for Apples and oranges are the same. A change in the price of oranges and apples would lead to the same proportional change for each of the demand for Apples and oranges.

Answer:
c. the trade balance and the exchange rate.
Explanation:
An Open Economy is an economy that allows the free inflow and outflow of goods, services, capital and people. The opposite of a closed economy.
What sets these two models apart is that in an open economy, both imports and exports are allowed, so that countries necessarily have to trade in more than one currency, so the exchange rate must be examined. In addition, business transactions are recorded in a balance of payments. So these are the two concepts that are not tried in a closed economy analysis, but are introduced in an open economy.
