A local retail store marks up its items 27% from its cost. At its annual \"Super Day\" sale, the store discounts its regular price by 35%. If the cost to the store is c, what is the sales price in terms of c? Solution marked price = c+0.27c = 1.27c now since the discount is35% hence the selling price = 1.27c-0.35*1.27c = 0.83c.
