Answer:

A) 44.25 hours

Explanation:

To round time to the nearest quarter-hour, round those times within 7 minutes of a 15-minute mark to that 15 minutes.

Thus, the time in and time out are rounded to the nearest quarter-hour in the table below:

Next, add the differences:

[tex]\begin{gathered} Total=9:15+8:45+9:00:8:15+9:00 \\ =43hours+(15+45+15)minutes \\ =44\text{ hours 15 minutes} \\ =44+\frac{15}{60} \\ =44.25\text{ hours} \end{gathered}[/tex]

She worked a total of 44.25 hours.

Option A is correct.
