Question: Suppose A furniture company manufactures desks and chairs. Each desk uses 4 units of wood, and each chair uses 3 units of wood. A desk contributes $400 to profit, and a chair contributes $250. Marketing restrictions require that the number of chairs produced be at least twice the number of desks produced. There are 2000 units of wood available.

Let d denote the number of desks produced and let c be the number of chairs produced.

The marketing constraint can be written in which of the following ways?
