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.
Answer:
(B). 50 cents
Explanation:
<u>Marginal cost</u><u> is the cost incurred by producing or purchasing one more unit of an item.</u>
If Jordan buys two tacos and a medium drink, it will cost him $2 and 50 cents or 250 cents (80 + 80 + 90).
However, if he opts for the value meal of three tacos and a medium drink, that costs $3 (300 cents), then he would be purchasing one additional taco at a marginal cost of 50 cent.
Marginal cost of additional unit of taco = 300 cents - 250 cents = 50 cents.
