The correct response is:
"The model represents 48÷(−16), which is solved by dividing 48 by 16 and changing the sign to get −3."
This is because the equation 48 + (−16) + (−16) + (−16) = 0 can be interpreted as finding how many times -16 fits into 48, resulting in -3, which aligns with the division operation 48 ÷ (−16).
