Acandlemaker prices one set of scented candles at $10 and sells an average of 200 sets each week. he finds that when he reduces the price by $1, he then sells 50 more candle sets each week. a function can be used to model the relationship between the candlemaker's weekly revenue, r(x), after x one-dollar decreases in price. this situation can be modeled by the equation y = _ x2 +_ x +_ and by graph_.

Find the solution set of this inequality. select the correct graph. |8x+16|> 16
