To find out how much money Reem has after paying her friend back, you can subtract the amount she owes from her earnings.
First, let's calculate:
- Reem's earnings: $43.78
- Amount owed to her friend: $15.25
Now, subtract the amount owed from her earnings:
\[ 43.78 - 15.25 = 28.53 \]
So, after paying her friend back, Reem has $28.53 left.
The correct response is:
$28.53
