To determine how far up the bar for red will go in Maxwell's bar graph, we need to calculate the percentage of red marbles in relation to the total number of marbles.

He has 7 red marbles out of a total of 28 marbles.

To find the percentage, we use the formula:

\[
\text{Percentage} = \left( \frac{\text{Number of red marbles}}{\text{Total number of marbles}} \right) \times 100
\]

Substituting in the values:

\[
\text{Percentage} = \left( \frac{7}{28} \right) \times 100
\]

Calculating the fraction:

\[
\frac{7}{28} = \frac{1}{4} = 0.25
\]

Now, multiplying by 100 to get the percentage:

\[
0.25 \times 100 = 25\%
\]

Therefore, the bar for red will go up to **25%** in the bar graph.

The correct response is:
**up to 25%**
