Answer:

Martin has 684 baseball cards
Matt has 392 baseball cards

Step-by-step explanation:

Let N, J, K, M represent the numbers of cards that Martin, Josie, Kal, and Matt have, respectively.

Equations

We are told ...

N = 12J

J = 29 +K

M = 14K

K = 28

Solution

Working from the bottom up, ...

M = 14·28 = 392

J = 29 +28 = 57

N = 12J = 12·57 = 684

The answers to the questions asked are ...

Martin has 684 baseball cards; Matt has 392 baseball cards.
