You are an avid snowboarder but the cost to participate in your favorite sport just grows and grows. For example, over the past 4 years since the sport got popular, the prices in Winter Park and neighboring ski resorts have increased as shown in the following table:
| Year | Ticket Cost | Differences |
|---|---|
| 1992 | $24 |

| 1994 | $37.44 |
| 1995 | $45.18 |
