James went to the store to return a defective $45 tape recorder for a refund. At the same time, he bought some batteries for $3 per package. If he received $33 dollars of his refund, how many packages of batteries did he buy?

If he returned something that cost $45, and in the end he received $33 of it back, that means that in between getting his $45 back and leaving the store with only $33 of it, he spent $45 - $33, which is $12.  If each pack of batteries costs $3, divide $12 by $3 to see how many packs of batteries that comes out to.  See that?

he should have gotten 45 back
but he only got 33
so the DIFFERENCE is how much he got in batteries, how many packs? well $\large \begin{array}{rrllll}
\quad 45\
-33\
\hline\
12 
\end{array}\qquad 12 \div 3?$
