Let \( x \) be the number of erasers Stefanie bought. Then the total cost of the erasers is \( 0.25x \).
Stefanie’s total expenditure can be represented by the equation:
\[
1.75 + 0.25x = 4.25
\]
To solve for \( x \), first subtract \( 1.75 \) from both sides:
\[
0.25x = 4.25 - 1.75
\]
\[
0.25x = 2.50
\]
Now, divide both sides by \( 0.25 \):
\[
x = \frac{2.50}{0.25}
\]
\[
x = 10
\]
Thus, Stefanie bought \( \boxed{10} \) erasers.
