I got 6300 multiple times and don't see what I did wrong

Ahngram Corp. has 1,000 defective units of a product that cost $3.80 per unit in direct costs and $7.30 per unit in indirect cost when produced last year. The units can be sold as scrap for $4.80 per unit or reworked at an additional cost of $3.30 and sold at full price of $14.40. The incremental net income (loss) from the choice of reworking the units would be: Multiple Choice $11,100. $4,800. $3,300. ($3,300)
