You sell short 300 shares of Microsoft that are currently selling at $30 per share. You post the 50% margin required on the shor
Lostsunrise [7]

Answer:

20%

Explanation:

Data provided

Currently selling per share = $30

Cost of Microsoft after selling = $27

Margin percentage = 50%

The calculation of rate of return is shown below:-

Rate of return = (Currently selling per share - Cost of Microsoft after selling) ÷ Margin percentage × 100

= ($30 - $27) ÷ 50% × 30

= $3 ÷ 15

= 0.20

or

20%

Therefore for calculating the rate of return we simply applied the above formula.

If the marginal propensity to consume is 0.8, full-employment output is $14 trillion, and current output is $13.5 trillion, then
CaHeK987 [17]

Answer:

c. Increase by $0.1 trillion

Explanation:

Investment spending Multiplier is a concept in economics that measure how a given change in investment increases output. So if current output of $13.5 trillion must increase to $14 trillion, we employ the multiplier formula to derive what amount of investment spending is needed to get $o.5trillion increase in output.

(change in output)/ (change in investment) = 1/(1-mpc)

Note that mpc means marginal propensity to consume.

Let change in investment = X

change in output = 14 - 13.5 = $0.5trillion

mpc = 0.8

(0.5)/X = 1(1-0,8)

0.5/X = 1/0.2

cross multiply

X = 0.1

Thus the needed change in investment is an increase of $0.1 trillion. In other words, if investment increases by $0.1 trillion, current output will increase from $13.5 trillion to $14 trillion.

ABC, a U.S. company sends by fax an offer to sell to XYZ, a French company, 1,000,000 widgets for $1.00 a widget. XYZ sends back
galben [10]

Answer:

The correct option is B. False.

Further explanation is given below in the explanation section.

Explanation:

Offer From ABC Company to XYZ Company:

1,000,000 widgets to sell.

Selling Price of 1 widget = $1.00

Total Price = $1,000,000

Counter Offer from XYZ company to ABC Company.

Selling Price = $0.75

Total Price = 0.75 x 1,000,000 = $750,000

But in the end, ABC company sold its widgets to GHK company.

The correct option to this question is false.

This case is false because here ABC sends an original offer of $1 but XYZ sent a counter offer of $0.75. This counter offer was then duly rejected by ABC.

XYZ cannot again confirm and accept the original offer of ABC because they have already rejected your claim and thus XYZ have to wait until ABC make them another offer.
