Samantha and her three friends had to give up (3) red marbles to their opponents for loosing their game. The equation to this scenario is 4 x (–3) = –12.

Answer 1

This equation represents the situation correctly. If Samantha and her three friends each had to give up three red marbles, the total number of marbles given up would be 3 + 3 + 3 + 3 = 12. However, since they are giving up red marbles to their opponents, the sign on the equation is negative. Therefore, the equation becomes 4 x (-3) = -12.
