8 0

20+8h=52

subtract 20 on both side

8h=32

divide both sides by 8

h=4

so you worked 4 hours

"Sydney has a portfolio with 50 shares of AAA with a current value of $20 per share, a return of 12%, and a beta of 1.30. She al

Nezavi [6.7K]

Answer: 12.72%

Explanation:

Given the following information ;

50 Shares of AAA at $20 and expected returns of 12%

25 Shares of BBB at $60 and expected returns of 10%

75 Shares of CCC at $50 and expected returns of 14%

Total value of the portfolio ;

Total Portfolio Value = ( 50×20 ) + ( 25×60 ) + ( 75×50 )

= 1000 + 1500 + 3750 = $6,250

Weight of each share in the portfolio;

Weight of Stock AAA = ( 50×20 ) / 6250 = 0.16

Weight of Stock BBB = ( 25×60 ) / 6250 = 0.24

Weight of Stock CCC = ( 75×50 ) / 6250 = 0.60

Expected return on portfolio is calculated thus;

Expected Portfolio Return = ( Weight of AAA×Expected Returns ) + ( Weight of BBB×Expected Returns ) + ( Weight of CCC×Expected Returns )

Expected Portfolio Return = ( 0.16×0.12 ) + ( 0.24×0.10 ) + ( 0.60×0.14 )

Expected portfolio return = (0.0192+0.024+0.084) = 0.1272

0.1272 = 12.72%

West company declared a $0.50 per share cash dividend. the company has 190,000 shares issued, and 10,000 shares in treasury stoc

Damm [24]

To record the dividend declaration
Ordinary Share Capital $90000
Dividend Payable $90000
to record payment
Dividend Payable $90000
Cash $90000

The amount is derived from the shares issued and outstanding so, the 190000 issued is deducted by 10000 treasury shares because treasury shares are reacquired by the company so it is not an outstanding share, then just multiply the answer with the dividend per share to arrive at $90000

190000-10000shares * $.50 =$90000

A company is evaluating a new 4-year project. The equipment necessary for the project will cost $3,250,000 and can be sold for $

MissTica

Answer: $615,810‬

Explanation:

The Book Value of the Asset at the end of 4 years will be;

= Cost of equipment - Accumulated Depreciation

= 3,250,000 - ( 3,250,000 * ( 20% + 32% + 19.20% + 11.52%))

= 3,250,000 - 2,688,400

= $561,600

The Equipment will be sold at $645,000 meaning a gain is made

= 645,000 - 561,600

= $83,400

Tax to be paid is;

= 83,400 * 0.35

= $29,190

After-tax salvage value of the equipment = Sales Price - Tax

= 645,000 - 29,190

= $615,810‬
