The first challenge involves solving multi-step math problems. Teams will receive three points for every problem that they get correct, and an additional 12 points for winning each challenge. Which equation best represents the situation above?

12c+3=t
12 c plus 3 is equal to t

3c+12=t
3 c plus 12 is equal to t

12t+3=c
12 t plus 3 is equal to c

3t+12=c
