Monday 9

Wednesday 10
Thursday 6
Friday 6
According to the table, what was the rate of change between Tuesday and Thursday?
emails per day

Answer 1

To find the rate of change in the number of emails Greta received between Tuesday and Thursday, we can use the formula for the rate of change:

\[
\text{Rate of Change} = \frac{\text{Change in Emails}}{\text{Change in Days}}
\]

First, we need to identify the number of emails received on Tuesday and Thursday:

- Emails on Tuesday: 6
- Emails on Thursday: 6

Next, we calculate the change in the number of emails:

\[
\text{Change in Emails} = \text{Emails on Thursday} - \text{Emails on Tuesday} = 6 - 6 = 0
\]

Now, we determine the change in days:

\[
\text{Change in Days} = \text{Thursday} - \text{Tuesday} = 2 \text{ days}
\]

Now, we can find the rate of change:

\[
\text{Rate of Change} = \frac{0}{2} = 0 \text{ emails per day}
\]

Thus, the rate of change between Tuesday and Thursday is **0 emails per day**.
