Question

What would be an appropriate shelf-life, t₉₀, for this drug (in days) in this solution?

### Data Table: Concentration Over Time

This table shows the concentration of a substance measured in micrograms per milliliter (mcg/mL) over a period of several months.

| Time (months) | Concentration (mcg/mL) |
|---------------|------------------------|
| 0.5 | 15.74 |
| 1 | 14.46 |
| 3 | 10.3 |
| 7 | 5.2 |
| 12 | 2.22 |
| 16 | 1.12 |
| 18 | 0.8 |

### Analysis

The data illustrates a decreasing trend in concentration over time, indicating either a consumption or degradation of the substance as months progress.

This type of data could be visualized in a line graph where the x-axis represents time (months) and the y-axis represents concentration (mcg/mL). The graph would show a downward slope, illustrating the decline in concentration over the time period.
