Jax and sofia collect baseball cards. jax has 56 cards and sofia has 68. they each joined different baseball-collecting clubs. each month, jax's club will send him 4 new packages of cards. sofia's club will send her 3 new packages per month. if each pack has 4 cards in it, after how many months will jax and sofia have the same number of cards? how many will they have?

Jax gets 4 packs per month...each pack contains 4 cards...so he gets 16 cards per month.
Sofia gets 3 packs per month..each pack contains 4 cards...so she gets 12 cards per month..

56 + 16m = 68 + 12m
16m - 12m = 68 - 56
4m = 12
m = 12/4
m = 3they will have the same number of cards in 3 months

Jax : 56 + 16(3) = 104 cards
Sofia : 68 + 12(3) = 104 cards

and they will both have 104 cards
