Answer:
$26,000
Step-by-step explanation:
The calculation of Net increase or decrease in income on replacement is shown below:-
Net savings in Variable cost for 4 years = Variable manufacturing costs × Life
= $19,800 × 4
= $79,200
Net Investment to be made in New machine = Initial investment of new machine - Traded in value of old machine
= $128,000 - $22,800
= $105,200
Net financial disadvantage of replacement = Net savings in Variable cost for 4 years - Net Investment to be made in New machine
= $79,200 - $105,200
= $26,000
So, for computing the net financial disadvantage of replacement we simply applied the above formula.
