Answer:
If the phones are reworked, income will increase by $12,900.
Step-by-step explanation:
Because we need to determine the incremental income, we will not take into account the original costs. They remain constant in both options.
Sell as-is:
Effect on income= 1,075*38
Effect on income= $40,850 increase
Rework:
Effect on income= 1,075*(136 - 86)
Effect on income= $53,750
If the phones are reworked, income will increase by $12,900.
