Juan initially borrows a total of $13 (which includes the $10 and the additional $3 from his mother). After selling $25 worth of lemonade, he needs to pay back his mother the $3 she loaned him.
So, after paying back his mother, Juan will have:
$25 (earnings) - $3 (amount owed to his mother) = $22 left.
The remaining money after paying his mother is $22.
However, the available responses only include amounts less than or equal to $13. If the question is only concerned with whether Juan has any remaining after paying back the loan to his mother, the correct response is that he will have $22.
In terms of available responses, the closest correct interpretation is that Juan will remain with $22 after paying off what he owes his mother.
