R = 0.46n3 – 1.9n2 + 3n + 19 T = 0.45n3 – 1.85n n Write an equation that represents the sales of video games V. A. VIDEO GAMES The total amount of toy sales T (in billions of dollars) consists of two groups: sales of video games V and sales of traditional toys R. In recent years, the sales of traditional toys and total sales could be modeled by the following equations, where n is the number of years since 2000. B. Use the equation to predict the amount of video game sales in the year 2012.

Notes and examples A. BUSINESS The profit a business makes is found by subtracting the cost to produce an item C from the amount earned in sales S. The cost to produce and the sales amount could be modeled by the following equations, where x is the number of items produced. C = 100x x – 300 S = 150x x Find an equation that models the profit. B. Use the equation 50x2 – 50x to predict the profit if 30 items are produced and sold.
