Answer: Micheal will earn an interest of $600 in the first year based on nominal interest rates.
Since we need to compute the interest paid out at the end of year 1, we use the following formula in order to find the interest

Answer:
Hence, the firm's total variable cost of producing three units of output is $48 unit.
Thus, the correct option is d. $48 unit.
Explanation:
The computation of total variable cost is shown below:
= marginal cost of the First unit of output + marginal cost of the second unit of output + marginal cost of the third unit of output
= $20 + $16 + $12
= $48
The variable cost include all type of cost which is change when the production level changes. In the given question, the output level changes with the unit which reflects the variable cost. So, the cost would be added in the computation part.
Hence, the firm's total variable cost of producing three units of output is $48 unit.
Thus, the correct option is d. $48 unit.
