Explanation:
We will cross-multiply the variables concept like sales revenues materials, labor and other
I.G
sales revenues for 90,000:
3,500,000 / 100,000 x 90,000 = 3,150,000
for 80,000:
3,500,000 / 100,000 x 80,000 = 2,800,000
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 = 30%
Now we will determinate the tax expense with that rate.
