Answer: equal to; at their minimum.
Explanation: Marginal cost is equal to the average variable cost and the average total cost when they are at their minimum.
Thus, when average total cost is increasing, marginal cost must be above average total cost; and when at its minimum, marginal cost is equal to average total cost. Also, when average variable cost is at its minimum, marginal cost equals average variable cost.
Marginal cost is the increase in the cost that accompanies a unit increase in output; the partial derivative of the cost function with respect to output.
Answer:
E) $2,400
Explanation:
optimal order quantity = sqrt{(2*D*S)/H}
= sqrt{(2*36,000*$80)/$4}
= $1,200
number of orders per year = $36,000/$1,200
= $30
total ordering cost = $30*$80
= $2,400
Therefore, The total ordering cost of inventory is $2,400.
Answer: Keep your account open and you will earn more on Interest you've already earned
Explanation:
Since Tom's investment account at his bank has a compounding interest, the best advice that'll be offered to Tom is to keep the account open and he will earn more on Interest than what he has already earned.
It should be noted that compound interest makes ones money grow faster. The reason for this is due to the fact that the interest is calculated based on the accumulated interest that the individual has earned over time and the original principal.
Therefore, it isn't advisable for Tom to withdraw his money or ask the bank to compound the interest less frequently but rather, he should keep the account open as he'll earn more interest.
