Answer:
$10,080 income
Explanation:
The computation of incremental income or loss on reworking the units is shown below:-
Incremental income on reworking unit = Sales after reworking - Sales to salvage company - Incremental cost
= (1,200 × $19.40) - (1,200 × $4.20) - (1,200 × $6.80)
= $23,280 - $5,040 - $8,160
= $10,080 income
Therefore for computing the Incremental income on reworking unit we simply applied the above formula.
