Question

Tuesday- 340
Wednesday- 425
Thursday- 337
Friday- 387
Saturday- 289
What is the rate of change between Wednesday and Friday?

Answer 1

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.
