Answer:
Yes, the machine should be replaced
Explanation:
The calculation is given below:
<u>
Particulars              old Machine            New machine
</u>
Purchase price                                       $300,000
Less:
Salvage value                                        -$80,000
Operating cost         $400,000              $144,000
                           ($100,000 × 4 )        ($36,000 × 4)
Total cost                 $400,000                $364,000
Hence, the financial advantage is
= $400,000 - $364,000
= $36,000
As there is a financial advantage of $36,000 therefore the old machine would be replaced with the new machine
 
        
             
        
        
        
<span>Mark is using what is called a lag strategy. A lag strategy can be used when there is an intended change in payment in a foreign transaction. This usually occurs when there is an expected change occurring in exchange rates. The lag occurs when the transaction is delayed, which is what Mark is attempting to do here.</span>
