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 = 3 ... they 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
