Is skyrim special edition worth it if you have the original
xenn [34]
Depends on if you've got it on PC or console. The console versions obviously work on the latest generation machines and come with the texture pack (which has always been free), modding capabilities (better on XBONE) and all DLC's.

So if you're looking to take your PS3/XB360 copy to the next level then I'd say yes, personally.

The PC version gets you the DLC's thrown in and that's all, assuming you don't own any of the DLC's this might be he better value overall depending on offers, so do some research, you're not gaining anything bar the DLC's though, you could already get the texture pack and mod.

Short answer: Consoles: Yes. PC: Only if the DLC's are cheaper that way.

Enviro Company issues 8%, 10-year bonds with a par value of $300,000 and semiannual interest payments. On the issue date, the an
elena55 [62]

Answer:

1. Issuer's cash is $262,500

2. Total amount of bond interest is $277,500

3. The amount of bond interest expense is $13,875.

Explanation:

1. Issuer's cash = Face Value × Selling Price

Issuer's cash  = $300,000 × 87.50%

Issuer's cash  = $262,500

2. Discount on bond = $300,000 × 12.5% = $37,500

Interest on bond = $300,000 × 8% = $24,000

Period of bonds= 10 years

Total amount of bond interest = Discount on Bond + (Interest on Bond  × period)

Total amount of bond interest = $37,500 + ($24,000  × 10)

Total amount of bond interest = $277,500

3. Discount on bond = $300,000 × 12.5% = $37,500

Interest on bond = $300,000 × 8% = $24,000

Period = 0.5 years

The amount of bond interest expense = (Discount of Bond ÷ 20) + Interest

The amount of bond interest expense = ($37,500 ÷ 20) + ($24,000 × 0.5)

The amount of bond interest expense = $1,875 + $12,000

The amount of bond interest expense = $13,875.

The amount of the average investment for a proposed investment of $191,000 in a fixed asset with a useful life of 4 years, strai
sineoko [7]

$30300
Annual depreciation = (purchase price - salvage value) / useful life
Straight line depreciation = Annual depreciation / (purchase price -salvage value)
The steps in calculating a straight line depreciation are:
Find out how much the asset costs.
To determine the entire depreciable amount, deduct the asset's estimated salvage value from the asset's purchase price.
Find out how long the item will be useful.
To calculate the annual depreciation amount, multiply the total from steps (2) and (3) by the figure determined in steps (3).
i.e, = $191000-$30300 = $160700
an asset with a useful life of 4 =$160700/4 =$40 175
so the straight-line depreciation rate is at 4.7%
In 4 years Straightline depreciation will be $30300

Mott Company's sales mix is 3 units of A, 2 units of B, and 1 unit of C. Selling prices for each product are $34, $44, and $54,
Airida [17]

The break even point in composite units is 5000 units.

Break even point

The Break-even point  is calculated by dividing the fixed cost by the contribution margin per unit.

For this sales mix, the contribution margin per unit is the aggregate of each contribution margin. Contribution margin is calculated by subtracting variable cost from the selling price  

Contribution margin  for A is $20- $12 = $8  x 3 units

Contribution margin for B is  $ 30 - $18 = $12 x 2 units

Contribution margin for C is $40 -$24= $16  x 1 unit

Total contribution margin per unit will be

(8 x 3) x (12 x 2 ) x( $16 x 1)= $64

Break-even point = $320,000 /64
