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 = *250, -200, -15 ,-50* x^2 + *300, 1450, 350, 1950* x+ * 1,500, 2000, 2500, 500* and by graph *y, w,x, y* answer
