Answer:
The correct answer is decrease.
Explanation:
The cost of opportunity represent the benefits that you misses out on when choosing one alternative over another.
In this case, the cost of opportunity is making smartphones and because of the shape of Bulgaria’s PPF should reflect the fact that as Bulgaria produces more trucks and fewer smartphones, the opportunity cost will be weaker. Bulgaria can´t produce only smartphones, you have to make more trucks than smartphone. So that will be a reason to prefer making trucks over smartphones ( the cost opportunity looses power)
Answer: $25
Explanation:
Margin call = Initial price * (1 - initial margin) / ( 1 - maintenance margin)
Initial margin = Personal amount invested / Total amount invested
= 20,000 / (20,000 + 20,000)
= 0.5
Margin call = 30 * (1 - 0.5) / ( 1 - 0.4)
= 30 * 0.8333
= $25
