Response:
A) 100
Clarification:
total sales 3,600 units
cost per unit $200
order placement cost $40
holding cost is $20 annually
working days 360 yearly
lead time is 5 days
Should Mark purchase 200 units per order, what would his average stock be?
daily sales = total sales / working days = 3,600 / 360 = 10 units daily
orders each year = 3,600 / 200 = 18
Mark's order frequency = 360 days / 18 orders = 20 days
average inventory = (200 units / 20 days) x 10 days = 100
I presume Mark has some safety inventory to ensure he can cover the 5-day lead time.
The adjusting entry to be made at the end of the accounting period includes a debit to Unearned revenue of $500 and a credit to Revenue for the same amount. According to the accrual accounting technique, revenues are recorded at the time of the transaction rather than when the payment is received. After receiving $800 in advance services, with $300 worth of services outstanding, the service amount performed amounts to $800 - $300 = $500.
Answer:
(a) 
(b) 
(c) X=4.975 percent
Explanation:
(a) Identify the z-value that represents 5.40 percent
.


Thus, a net interest margin of 5.40 percent stands at 2.5 standard deviations above the average.
From the standard normal distribution table, the area to the left of 2.5 is 0.9938. Hence, the likelihood of a randomly selected U.S. bank achieving a net interest margin greater than 5.40 percent is 1-0.9938=0.0062
(b) The z-value corresponding to 4.40 percent is
The net interest margin of 4.40 percent is situated at 0.5 standard deviation above the average.
According to the normal distribution table, the area to the left of 0.5 is 0.6915
Thus, the probability of a randomly chosen U.S. bank having a net interest margin below 4.40 percent equals 0.6915
(c) The z-value indicating 95% is 1.65
Substituting 1.65 into the equation enables us to find X.




For a bank that wishes for its net interest margin to fall below that of 95 percent of all U.S. banks, it should aim for a net interest margin of 4.975 percent.
