Sammy's Toy Shop is trying to find an equation that will help determine how much inventory to purchase for the next month. The inventory for teddy bears to purchase should be the number of teddy bears ordered last month less the number of teddy bears sold last month plus three more for surplus.

Use the table below to create a graph and to answer the following questions:

	Number of Teddy Bears Ordered Last Month	Number of Teddy Bears Sold Last Month
January	30	5
February	28	5
March	26	5
April	24	5
May	22	5
June	20	5
July	18	5
August	16	5

What is the inventory ordered for September according to this table?

Create a graph of these points on an xy-coordinate plane.

Based on the table and the information above, write an equation that fits the information.

Based on this equation, identify where the y-intercept is and x-intercept.

In a brief sentence or two and in your opinion, is this a practical model for Sammy's Toy Shop?
