Answer:

  • Sparkle: 104
  • Southern: 208
  • Scenic: 416

Step-by-step explanation:

The ratios of people at each rink were ...

  Sparkle : Southern : Scenic = 1 : 2 : 4

The total number of ratio units is 1+2+4 = 7, so each one must stand for 728/7 = 104 skaters. Then the ratios of the numbers of skaters were ...

   Sparkle : Southern : Scenic = 104 : 208 : 416 . . . multiply ratio units by 104

People skating were ...

  • Sparkle: 104
  • Southern: 208
  • Scenic: 416
