Step-by-step explanation:
The computation of the overall effect on operating income is shown below:
Sale after further processing (1,800 units × $5.50) $9,900
Less: Sale at split off point (1,800 units × $2.90) -$5,220
Incremental revenue $4,680
Less : Incremental cost -$2000
Incremental income $2,680
