Pinewood Academy's winter carnival is coming up, and Mr. Meyer is in charge of ordering the craft kits again. He knows he ordered 9 boxes of snowman kits last year but can't remember how many kits come in a box. He checks the records and finds that the school used 168 of the snowman kits last year and had 12 left over after the event.
Which equation can Mr. Meyer use to find how many snowman kits, k, come in each box?
