Here Let total visitor be 100
so 76% visitors are pacific or Southwestern State = 76% of 100 = 76 visitor
Now out of 76 visitor 2/3 were from California i.e 2/3 *76 = 51 visitor.
Therefore visitors at the resort from southern California =51 * 87% = 44.37% nearly equal = 45%
Now out of these 87% were from southern California
