 Question 464096: At what price should a dealer mark an aquarium in order that the selling price may be \$980 after allowing a discount of 15% on the marked price??? Please help...Answer by Theo(3464)   (Show Source): You can put this solution on YOUR website!dealer wants the selling price to be \$980. this price should include a discount of 15% on the marked price. this means that the marked price minus 15% should be equal to \$980. let x equal the marked price. then x - .15 * x = 980. factor out the x to get (1-.15)*x = 980. simplify to get .85*x = 980. divide both sides of the equation by .85 to get x = 980/.85 simplify to get x = 1152.941176. that's what the marked price should be. the aquarium is marked as costing 1152.941176. with a discount of 15%, the selling price will be 1152.941176 minus .15 * 1152.941176, which becomes 980.
