Answer 2

9. The cost will be the selling price minus the gain. $340 - $20 = $320

10. The selling price will be the cost + % times the cost. $120 + (.1)(120) = 120+ 12 = $132

11. Selling price will be the cost - %(cost)
$60 - 12.5%(60) = 60 - 7.50 = $52.50

12. Selling price will be cost + 2.5%(cost)
80 + 2.5%(80) = 80 + 2 = $82
