You just sold 300 shares of stock at a price of $42.06 a share. You purchased the stock for $39.80 a share and have received tot
Alex Ar [27]

Answer:

$678

Explanation:

Given that,

Number of shares sold = 300

Selling price of each share = $42.06

Cost of purchasing shares = $39.80 per share

Total dividend received = $1,272

We can easily determine the total capital gain on this investment by comparing the sales value and purchase value of this stock.

Total capital gain on this investment:

= Sales value - Purchase value

= (Number of units × Selling price per unit) - (Number of units × cost of purchasing per share)

= (300 × $42.06) - (300 × $39.80)

= $12,618 - $11,940

= $678

never [62]

Answer:

$60,000

Explanation:

Double declining method is a depreciation method used to expense the cost of an asset.

Depreciation expense using the double declining method = Depreciation factor × cost of asset

Deprecation factor = 2 (1/useful life) = 2(1/8) = 1/4

Depreciation expense in 2016 = 0.25 × $320,000 = $80,000

Net book value = $320,000, - $80,000 = $240,000

Deprecation expense in 2017 = 0.25 x $240,000 = $60,000

The accounts in the ledger of Monroe Entertainment Co. are listed below. All accounts have normal balances.
lara [203]

Answer:

The correct answer is $13.900.

Explanation:

To carry out the verification balance, the nature of the accounts presented in the normal balance of the organization must be taken into account. We have that the assets and income have a debit nature, so it is necessary that the corresponding to that premise are:

Accounts receivable $ 1,800 - Active

Insurance expenses $ 1,300 - Expenses

Prepaid insurance $ 2,000 - Expenses

Land $ 3,000 - Active

Cash $ 3,200 - Assets

Salary Expenses $ 1,400 - Expenses

On the other hand there are accounts that despite being of a credit nature, have credit movements as a result of ordinary activities, which would be:

Dividends: $ 1,200 - Debit nature liability

TOTAL DEBITS: $ 13,900
