Suppose that a business incurred implicit costs of $200,000 and explicit costs of $1 million in a specific year. if the firm sold 4,000 units of its output at $300 per unit, its accounting profits were:
a. $100,000 and its economic profits were zero.
b. $200,000 and its economic profits were zero.
c. $100,000 and its economic profits were $100,000.
d. zero and its economic loss was $200,000.

b

Explanation:

Given

Implicit cost=$ 200,000

Explicit cost=$ 1 million

4000 units

Output=$ 300 per unit

therefore revenue

as we need to compute accounting profit therefore we do not consider the implicit cost

accounting Profit=1.2-1=$ 0.2 million

and economic Profit =Revenue -explicit cost-Implicit cost

economic Profit=0.2-0.2=0

Thus option b is most appropriate  

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
