$88.90

Step-by-step explanation:

Let her initial deposit be represented by x.

Based on the information given, in the question, an equation can be formed as:

x + $25.50 + $45.25 - $15.15 - $28.65 = $115.85

x + $70.75 - $43.80 = $115.85

x = $115.85 + $43.80 - $70.75

x = $88.90

The initial deposit is $88.90
