5. B. narrower

Explanation:

In this question, it is essential to estimate the actual population of Greeks that believe they are extremely poor and also suffering. This will be used for proper sampling.

C&A sells T-shirts for $20 that cost $5 to produce. The annual holding cost percentage is 10% and the T-shirts turn 25 times
Angelina_Jolie [31]

Answer:

B. $0.02

Explanation:

The computation is shown below:

Since the annual holding cost percentage is 10% and the cost of production is $5. So, the holding cost would be

= $5 × 10%

= 0.5

Now if the t-shirts run 25 times a year, so the holding cost would be

= 0.5 ÷ 25 times

= $0.02

Simply we compute the holding cost based on number of times the t-shirt turns in a year

All other information which is given is not relevant. Hence, ignored it

belka [17]
A similarity between mortgages and auto loans is that both are less risky for lenders.
Lenders are the ones who lend money to those who need it urgently, in the form of a mortgage, or perhaps an auto loan. This money is going to be repaid monthly, or in whatever way the contract stipulates. It is less risky for the lender because legally, this has to be repaid.

Q3) At an output level of 45,000 units, you calculate that the degree of operating leverage is 2.79. If output rises to 48,000 u
Luden [163]

Answer:  18.6%

Explanation:

Degree of operating leverage =  % change in Operating cash flow / % change in output

% change in Output

= \frac{48,000 - 45,000}{45,000}

= 6.7%

Degree of operating leverage =  % change in Operating cash flow / % change in output

2.79 = % change in Operating cash flow/ 6.7%

% change in Operating cash flow = 2.79 * 6.7%

% change in Operating cash flow = 18.6%
