Break Down the Problem

1. Identify the initial number of baseball cards Melissa had.
2. Understand how many additional cards she received today.
3. Combine both quantities to create the expression for the total number of cards.

Relevant Concepts

1. The total number of baseball cards is the sum of the initial amount and the additional amount received.
2. If $a$ is the initial number of cards and $b$ is the additional cards, then the total can be expressed as: $\text{Total} = a + b$

Analysis and Detail

2. She received $b$ more baseball cards today.
3. Thus, we can set up the expression: $\text{Total Cards} = 137 + b$

Verify and Summarize

The expression $137 + b$ accurately represents the total number of baseball cards Melissa has after receiving $b$ additional cards today.

Final Answer

The expression for the total number of baseball cards Melissa has now is: $137 + b$
