To find out how many marbles Jim and Charlene have in total, we first need to determine how many marbles Charlene has.
Jim has 300 marbles, and Charlene has twice as many:
\[
\text{Charlene's marbles} = 2 \times 300 = 600 \text{ marbles}
\]
Next, we add the number of marbles that Jim and Charlene have together:
\[
\text{Total marbles} = \text{Jim's marbles} + \text{Charlene's marbles} = 300 + 600 = 900 \text{ marbles}
\]
Therefore, the total number of marbles Jim and Charlene have is **900 marbles**.
