Signal mistakenly produced $1,025$ defective cell phones. The phones cost $$67$ each to produce. A salvage company will buy the

defectlve phones as they are for $$30$ each. It would cost Signal $$84$ per phone to rework the phones. If the phones are reworked,

Signal could sell them for $$144$ each. Signal has excess capacity. Should Signal scrap or rework the phones?
