The Alpine ski resort has started to keep track of the number of skiers and snowboarders who bought season passes. The ratio of the number of skiers who bought season passes to the number of snowboarders that bought season passes is 2 : 3. If 250 more snowboarders bought season passes, how many snowboarders and skiers bought season passes?
Skiers/Snowboarders = 2/3.
X/(X+250) = 2/3.
X = ?.
