Someone help me with this problem, please!

Signal mistakenly produced 1,200 defective cell phones. The phones cost $60 each to produce. A salvage company will buy the defective phones as they are for $38 each. It would cost Signal $86 per phone to rework the phones. If the phones are reworked, Signal could sell them for $138 each. Assume there is no opportunity cost associated with reworking the phones. Compute the incremental net income from reworking the phones.
