To determine the rate of change in the number of voicemail messages on Belle's phone between Thursday and Friday, we can follow these steps:

1. Identify the number of voicemail messages on Thursday and Friday from the given data:
- Thursday: 25 voicemail messages
- Friday: 20 voicemail messages

2. Calculate the rate of change by finding the difference in the number of voicemail messages between these two days:
- Rate of change = Number of voicemail messages on Friday - Number of voicemail messages on Thursday

3. Substitute the values from the data:
- Rate of change = 20 (Friday) - 25 (Thursday)

4. Perform the subtraction:
- Rate of change = 20 - 25 = -5

So, the rate of change in the number of voicemail messages between Thursday and Friday is [tex]\(\boxed{-5}\)[/tex] voicemail messages per day.
