I know that you need to get the break even part of this problem done first before you can answer the question. BE=FC/CM/units

not using GAAP I got 320000/(25-10)=21333.33. Then what I think you're supposed to is then take your additional 1000 units and apply it to the SP and VC on the denominator of this equation. But Im not certain. Please help, thank you!
