You decide to market your own custom computer software. You must invest $3,255 for computer hardware, and spend $2.90 to buy and package each disk. If each program sells for $13.75, how many copies must you sell to break even?

Each copy contributes $13.75 − $2.90 = $10.85 toward the $3,255 hardware cost. Since $10.85 × 300 = $3,255, you must sell 300 copies to break even. The correct choice is 300 copies.
