To solve the equation \( x - 32.65 = 125.35 \), we will use inverse operations.
1. Start with the equation:
\[
x - 32.65 = 125.35
\]
2. To isolate \( x \), add 32.65 to both sides of the equation:
\[
x - 32.65 + 32.65 = 125.35 + 32.65
\]
3. This simplifies to:
\[
x = 125.35 + 32.65
\]
4. Now calculate the right side:
\[
125.35 + 32.65 = 158
\]
Thus,
\[
x = 158
\]
So, Ellie had **$158** in her savings account before her purchase.
