We know that the initial state is 250 and the final state is 0.
Then, we can express the relation between this two states with a difference that shows the changes between this two states.
Because the score goes down by 250 points, we can write:
[tex]\begin{gathered} \text{Initial state}+\text{Variation}=\text{Final state} \\ 250+(-250)=0 \\ 250-250=0 \end{gathered}[/tex]Answer: Equation 1, because it shows the initial and final scores and the variation between them.
