vaieri [72.5K]

Answer:

both

  • United Continental with a capital expenditure of 60.68%
  • Southwest Airlines with a capital expenditure of 51.38%

Explanation:

Since United Continental's purchases of Boeing planes represent over 60% of their capital expenditures, this means that Boeing had to be the primary plane supplier. Even if the company purchased planes form other manufacturer, their purchases would not even be 40% of the company's purchases.

The same applies to Southwest Airlines, even though the purchases from Boeing are a little lower, they are still over 51%. This means the company could not have spent more money on purchasing planes from another company. The maximum purchase from another airplane manufacturer would have been less than 49% at most.

Besides the previous analysis, you must also consider that the company spends money on things besides airplanes, e.g. new training facilities, equipment, computer software, other vehicles, etc.

Gennadij [26K]

Answer:

C. Retained earnings increased $28,200 during 2018.

Explanation:

Total liabilities = Total assets - Total equities

= $217,000 - $123,000

= $94,000

Common stock as at December 31, 2018 = Total equity - Total retained earnings

= $123,000 - $83,000

= $40,000

Retained earnings at year end =

Opening retained earnings + net income - dividend paid

$83,000 = Opening retained earnings + $33,900 - $5,700

$83,000 = Opening retained earnings + $28,200

Opening retained earnings = $54,800

Change in retained earnings = Closing retained earnings - Opening retainer earnings

= $83,000 - $54,800

= $28,200

Therefore, Option 'C' is the correct option.

taurus [48]

Answer:

Fragmented organizational culture

Explanation:

Jazmine and Estaphanie work in a fragmented organizational culture. This kind of culture refers to the employees who are not connected to each other but are connected to their work. They have friendly relations with people who do not work with them.

This similar concept is also explained in the question where people participate in activities outside of work and rarely make any friends at work.

I hope the answer is helpful.

Thanks for asking.
