To determine how much money Juan will have left after paying back his mother, we start by calculating his total earnings and then subtract the amount he owes.
- Juan sold $25 worth of lemonade.
- He borrowed a total of $13 ($10 from one source and $3 from his mother).
- After selling the lemonade, his total money is $25.
- He needs to pay back his mother $3, since that was part of the total borrowed amount.
Calculating the remaining amount after paying his mother:
- Total earned: $25
- Amount owed to mother: $3
Remaining amount after paying back his mother: \[ 25 - 3 = 22 \]
So, Juan will have $22 left after paying back his mother. However, none of the provided options match this amount.
If we narrow it to only paying back his total borrowed amount of $13, which is not the case since we only pay back the amount owed to his mother:
Answer: The closest logic here leads to a potentially ambiguous pricing.
Could you confirm if you want to pay back the total or just the amount to his mother? If it's the total borrowed amount ($13), we can consider each option again, aligned with your inquiries:
In the case then: Paying back total borrowed ($13): \[ 25 - 13 = 12 \]
Thus, the response might align more closely to:
Final response: $12 (if considering paying the whole borrowed amount)
