A store sells pens at $2 and notebooks at $5.Let n represent the number of notebooks sold and p the number of pens sold.The following equations are true:

4n=p

5n+2p=39

Here is what Terrance and Sheila think the equations mean:

Terrance thinks the first equation means that the store sells four times as many notebooks as pens.Sheila thinks the second equation means that the store sold 5 notebooks and 2 pens.

Answer the following questions in your group discussion:

1. Are Terrance and Sheila correct?Explain.
2. If you think Terrance is wrong, explain the mistake and explain what you think the equation means.
3. If you think Sheila is wrong, explain the mistake and explain what you think the equation means.

Finally, determine the number of pens and the number of notebooks sold in the store.You may use a method of your choosing, but be sure to relate this back to what we did this week in your homework.
