Answer:
the total impact is $13,000 increase
Explanation:
The computation of the impact is shown below:
= Total saving in variable cost - Net investment
= $145,000 × 4 - ($615,000 - $48,000)
= $580,000 - $567,000
= $13,000 increase
As we can see that the total saving in variable cost would be more than the net investment so it would be an increase of $13,000
Therefore the total impact is $13,000 increase
