To find the number of players in Spruceburgh's league (n), we know that Spruceburgh has 3 times as many players as the Greenville league, which has 1,230 players.
We can write the equation as follows:
\[ n = 1,230 \times 3 \]
Now calculate:
\[ n = 3,690 \]
So, the correct response is:
1,230×3=n, so n =3,690.
