Question
The following table shows retail sales in drug stores in billions of dollars in the U.S. for years since 1995.
Let S(t)S(t) be the retails sales in billions of dollars in t years since 1995. A linear model for the data is F(t)=9.44t+84.182F(t)=9.44t+84.182.

Use the above scatter plot to decide whether the linear model fits the data well.
Estimate the retails sales in the U. S. in 2014. billions of dollars.
Use the model to predict the year in which retails sales will be $243 billion.
| Year | Retail Sales |
|---|---|
| 0 | 85.851 |
| 3 | 108.426 |
| 6 | 141.781 |
| 9 | 169.256 |
| 12 | 202.297 |
| 15 | 222.266 |
