Respuesta :
there were 10 stickers in each pack. you first subtract 4 from 24, to get how many finn would have without his friend giving him any and then (I'm assuming he bought 2 packs) divide by 2 to get 10.
first subtract 24-4 because the four stickers that were given to Finn don't matter. There is 20 stickers. Then divide that by 5 giving you four stickers in each pack.
