Answer:
$1,125,000
Explanation:
Given;
Gain from asset disposal = $225,000
Book value of asset disposed = $900,000
Therefore,
Amount of cash received from the sale = $900,000 + $225,000
                                                                   = $1,125,000
This represents an inflow of cash and will be represented by a positive value in the statement of cash flows. The total amount reported in the cash flows from investing activities section of the statement of cash flows is $1,125,000

Answer:
The gross margin for December is: 0.5%.
The Gross margin of an organisation or business measure the extent by which its income exceeds the costs it incurs in producing its goods and or services.  
The gross margin is measured in percentages. The higher the percentage of this margin, the higher the effectiveness of the company's management in deriving value from every dollar invested.
 
Explanation:
To arrive at Gross Margin, one is required to subtract the total cost of goods sold from total revenue for the period and dividing that number by revenue. That is:
Gross Margin (GM) = 
Step I - Calculate Revenue
This is given as the total amount of goods sold which is:
800 x $500 = $400,000
Step II - Calculate Cost of Goods Sold
Cost of goods sold per unit is given as 
$250 per unit. 
Total Cost of Goods sold therefore is
800 x $250 = $200,000
Step III - Calculate Gross Margin
= 
= 
=  or 0.5%
 or 0.5%

Answer:
d) result in overproduction or underproduction of a good.
Explanation:
Market failure occurs when market forces fails to allocate goods and services efficiently. 
The government usually intervenes to correct market failure.
Externalities usually lead to market failure.
Positive externality is when the benefits of economic activities to third parties exceeds its cost. Research and development usually yield postive externality. 
Goods that yield postive externality are usually underproduced. Government can intervene by giving subsidies and grants which encourages production. 
A negative externality is when the cost of economic activities to third parties exceeds the benefit. Pollution is an example of negative externality. Goods that yield negative externality are usually overproduced. Government can intervene by taxing companies producing negative externality. This would increase the cost of production and discourage production.
