Umnica [9.8K]

Answer:

(A) Interest coverage charge ratio= 6.21

(B) Fixed charge coverage = 2.84

(C) Profit margin ratio= 8.57%

(D) Total assets turnover= 1.55

(E) Return on assets= 13.26%

Explanation:

(A) The Interest coverage charge ratio can be calculated as follows= EBIT/Interest expense

= 45,300/7,300

= 6.21

(B) The fixed charge coverage can be calculated as follows

= income before fixed charge + interest/fixed charges + interest

= 45,300+13,300/7,300+13,300

= 58,600/20,600

= 2.84

(C) The profit margin ratio can be calculated as follows

= Net income/sales × 100

= 22,800/266,000 × 100

=0.0857 × 100

= 8.57%

(D) The total assets turnover can be calculated as follows

= Sales/total assets

= 266,000/172,000

= 1.55

(E) The return on assets can be calculated as follows

= Net income/Total assets × 100

= 22,800/172,000 × 100

= 0.13255×100

= 13.26%

Svetlana won $1,000,000 in a contest, to be paid in twenty $50,000 payments at yearly intervals, the first payment paid at the t
goldfiish [28.3K]

Answer: 31155.5

Explanation:

The following can be deduced from the question:

Money won = $1,000,000

Installments made yearly = $50,000

Interest rate = 5%

The yearly deposits made by Svetalana will be: = 500000-x

The future Value of the yearly deposits made by Svetalana will be:

= (50000-x) × (1/(1.05) + (1/(1.05)^2 .....(1/(1+0.05)^20))

= (500000-x) × 33.066

We should recall that the interest from the question is equated to x. This will be:

33.066 × (50000-x) × 0.05 =x

1.6533(50000 - x) = x

82665 - 1.6533x = x

2.6533x = 82665

x = 82665/2.6533

x = 31155.5

Elizabeth is a chef and the kitchen manager in an upscale restaurant. she is very knowledgeable in both the culinary and restaur
allsm [11]

Because she possesses these technical skills, Elizabeth can be considered a <u>"knowledge"</u> worker.


A knowledge worker is any individual who works professionally at the errands of creating or utilizing knowledge. For instance, a knowledge laborer may be somebody who works at any of the assignments of arranging, obtaining, looking, breaking down, sorting out, putting away, programming, dispersing, advertising, or generally adding to the change and business of data and those (frequently similar individuals) who work at utilizing the information so created.  

Knowledge work can be separated from different types of work by its accentuation on "non-schedule" critical thinking that requires a mix of concurrent and unique thinking. Yet in spite of the measure of research and writing on information work, there is no brief meaning of the term.
