Answer:
$69,000
Explanation:
The computation of the operating income would be shown below:
= Buying cost - making cost
where, 
Buying cost equals to
= 60,000 × $3
= $180,000
And, the making cost would be
= Variable cost + fixed cost × avoid percentage
= $90,000 + $70,000 × 30%
= $90,000 + $21,000
= $111,000
Now put these values to the above formula  
So, the value would equal to
= $180,000 - $111,000
= $69,000
 
        
             
        
        
        
Answer:

marginal tax rate = 24%
effective tax rate = 20%
to find out
amount of tax saving

so now put here all value in equation 1 
tax saving = tax deduction × marginal tax
tax saving = 18000 × 24%
tax saving = 18000 × 0.24
tax saving = 4320
so amount of tax saving is $4320

Explanation:
We compare the contribution margin of the two categories to find out whether Pine Street should sell unfinished or finished bookcases. 
Pine Street Inc. 
Unfinished bookcases 
Contribution Margin
Sales Price                                         $58.10
Less  Production costs 
Variable Costs  $37.49 
<u>Fixed Costs $10.50                         (47.99)</u>
<u>Contribution Margin                      $ 10.11</u>
 Pine Street should sell  finished bookcases because they have a higher contribution margin. It is almost double of the unfinished book cases contribution margin.
Pine Street Inc. 
Finished bookcases 
CONTRIBUTION MARGIN
Sales Price                                                                 $74.91
 Less Production costs 
Variable Costs  $37.49 + $5.79 = $ 43.28
<u>Fixed Costs $10.50                                                     $ (53.78)</u>
<u>Contribution Margin                                               $ 21.13</u>
