UpStudy AI · Accepted Answer

To determine the percentage of the battery life that has been used, you can use the following formula:

$$
\text{Percentage Used} = \left( \frac{\text{Hours Used}}{\text{Total Battery Life}} \right) \times 100\%
$$

Plugging in the values:

$$
\text{Percentage Used} = \left( \frac{7\ \text{hours}}{12\ \text{hours}} \right) \times 100\% = \frac{7}{12} \times 100\% \approx 58.33\%
$$

**Approximately 58.33 % of the battery life has been used up.**
Approximately 58.33% of the battery life has been used up.
