Solve the application by using a system of linear inequalities in two variables.A bakery plans to market a mixed assortment of its two most popular cookies: Chocolate Chip and Toffee Chunk. Their marketing analyst proposes that the new assortment be constrained by the inequality src="https://sciemce.com/media/4/ppg__10617191636__f1q36g3.jpg" alt="" style="vertical-align: -4.0px;" /> and 
where C is the number of Chocolate Chip cookies and T is the number of Toffee Chunk cookies. Their sales analyst suggests in order to offer a reasonably priced product the assortment should be constrained by the inequality
