During a shift, a new nurse spent five hours of her time observing procedures, three hours working in oncology department, and four hours doing paperwork. during the next shift, she spent four hours observing procedures, six hours in the oncology department, and two hours doing paperwork. what was the percent change for each task between the two shifts?

To find the percent change for each task, we need to compare the hours spent on each task between the two shifts.

During the first shift:
- Observing procedures: 5 hours
- Working in oncology: 3 hours
- Doing paperwork: 4 hours

During the second shift:
- Observing procedures: 4 hours
- Working in oncology: 6 hours
- Doing paperwork: 2 hours

Now we can find the percent change for each task.

Percent change for observing procedures:
(4 - 5) / 5 * 100% = -1/5 * 100% = -20%

Percent change for working in oncology:
(6 - 3) / 3 * 100% = 3/3 * 100% = 100%

Percent change for doing paperwork:
(2 - 4) / 4 * 100% = -2/4 * 100% = -50%

Therefore, the percent change for each task between the two shifts are:

Observing procedures: -20%
Working in oncology: 100%
Doing paperwork: -50%
