Let the number of erasers Stefanie bought be represented by \( x \).
The cost of the pencils is \( 1.75 \) dollars, and the cost of \( x \) erasers is \( 0.25x \) dollars.
The total cost for the pencils and erasers is given by the equation:
\[
1.75 + 0.25x = 4.25
\]
To find \( x \), we first subtract \( 1.75 \) from both sides of the equation:
\[
0.25x = 4.25 - 1.75
\]
Calculating the right side:
\[
4.25 - 1.75 = 2.50
\]
Now we have:
\[
0.25x = 2.50
\]
Next, we divide both sides by \( 0.25 \):
\[
x = \frac{2.50}{0.25}
\]
Calculating the division:
\[
x = 10
\]
Thus, Stefanie bought \( \boxed{10} \) erasers.
