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:


\begin{gathered} \text{Initial state}+\text{Variation}=\text{Final state} \\ 250+(-250)=0 \\ 250-250=0 \end{gathered}

Answer: Equation 1, because it shows the initial and final scores and the variation between them.
