Question

N notebooks each cost 4 dollars each 

Answer 1

Azralaya,

 

It might help you to think about what you would do if you were given a specific number of notebooks.  If he bought 5 notebooks, it would cost 5 * 4 = 20, right?  If he bought 3, you would multiply 3 * 4.  Whatever number he bought, you would multiply it by 4 to see how much it would cost.  So if n is the number bought, the cost will by 4 * n,or to write it more simply, 4n.  

Make sense?  If not, ask more.
