Answer:

$40

Step-by-step explanation:

Let the amount of money she has at first be $x.

She put 1/4 for savings, this means she decides to spend 3/4. The 3/4 is equivalent to (3/4)x

Now, she puts half of the money not saved to pay back her sister and has $15 left.

This means the (3/4)x is equivalent to $30. This is because she used half which is $15 to pay back her sister.

Now, since (3/4)x equals 30, we calculate x

(0.75)x = 30

x = 30/0.75 = $40

She originally had $40
