Explanation:
<em></em>
<em>We will cross-multiply the variables concept like sales revenues materials, labor and other</em>
I.G
<em>sales revenues for 90,000:</em>
3,500,000 / 100,000 x 90,000 = 3,150,000
<em>for 80,000:</em>
3,500,000 / 100,000 x 80,000 = 2,800,000
<em></em>
The fixed will remain at the same value between the relevant range so we do not change them.
For the tax expense we will have to check which is the rate
for 220,000 operating income the tax expense is 66,000
we can solve for rate: 66,000/220,000 = 0.3 = <em>30%</em>
Now we will determinate the tax expense with that rate.

Answer: Option B
Explanation: Under the straight line method of depreciation, the value of the asset is divided equally to its useful life. It is computed as follows :-

NOW,
A. Straight line method as per the above equation provides for equal productivity.
B. Dividing the usefulness equally results in ignorance of change in the rate of asset use as the asset may be used less initially but more in later years.
C. As the expense from the method remains same and the actual value of the asset diminishes it results in higher rate of return.
D. Decreasing charge method charge depreciation on written down value whereas straight line charges t initial cost thus it gives higher write offs than decreasing charge.
