Lola and Dora combined their allowance of $9 each to buy a deck of playing cards for $10, they also bought $2 boxes of stickers and split the boxes evenly. How many packs of stickers did Dora get? Give me reasons, before answering the question

Lola and Dora together have $9 / person x 2 people = $18. After buying the deck of cards they had $18 - $10 = $8. With 8 dollars they bought $8 / $2 / pack = 4 packs of stickers. Dora received 4 packs / 2 people = 2 packs of stickers. So the final answer is 2.
