Let \( x \) be the number of erasers Stefanie bought. The total cost of the erasers is \( 0.25x \). The total cost of the pencils is \( 1.75 \). The equation representing the total amount spent is:

\[
1.75 + 0.25x = 4.25
\]

To find \( x \), we can first isolate \( 0.25x \) by subtracting \( 1.75 \) from both sides:

\[
0.25x = 4.25 - 1.75
\]

Calculating the right side gives:

\[
0.25x = 2.50
\]

Next, we solve for \( x \) by dividing both sides by \( 0.25 \):

\[
x = \frac{2.50}{0.25}
\]

Calculating the division gives:

\[
x = 10
\]

Thus, Stefanie bought \( \boxed{10} \) erasers.
