You can set this up as an algebraic equation using the ratio:

$\frac{1}{2}$ = $\frac{x}{x+1250}$
where x = number of skiers

Cross multiply:
x + 1250 = 2x

Solve for x:
-x = -1250
x=1250

To find the number of snowboarders, add 1250.
1250 + 1250 = 2500

1250 skiers and 2500 snowboarders bought season passes.
