Signal mistakenly produced 1,000 defective cell phones. The phones cost $60 each to produce. A salvage company will buy the defective phones as they are for $30 each. It would cost Signal $80 per phone to rework the phone. If the phones are reworked, Signal could sell them for $120 each. Assume there is no opportunity cost associated with reworking the phones. Compuete the incremental net income from reworking the phones.
