To find the rate of change between Wednesday and Friday, we first need to find the values for both days:
- Wednesday: 425
- Friday: 387
We can calculate the rate of change by using the formula:
\[ \text{Rate of Change} = \frac{\text{Value on Friday} - \text{Value on Wednesday}}{\text{Number of days}} \]
Substituting the values:
\[ \text{Rate of Change} = \frac{387 - 425}{2} \]
\[ \text{Rate of Change} = \frac{-38}{2} = -19 \]
The rate of change between Wednesday and Friday is \(-19\). This indicates a decrease of 19 per day over the two days from Wednesday to Friday.
