you're opening a widget selling business and want to know what you should sell each widget for. Your research has found that if you make the price “x”, your total sales will be S(x)=-200x^2 + 70,000x. Also when the price is “x”, the total cost will be C(x)=-22,000x + 8,375,000. Find the price which makes the total sales and total cost equal. Then find the corresponding cost.
