Question

To determine how many staff members she needed, a local coffee shop owner recorded the number of customers that entered the shop each day.
Coffee shop customers
Day Customers
Monday 351
Tuesday 353
Wednesday 350
Thursday 354
Friday 331
According to the table, what was the rate of change between Tuesday and Wednesday?

Answer 1

To determine the rate of change between Tuesday and Wednesday, we can use the formula for rate of change, which is:

\[
\text{Rate of Change} = \frac{\text{Number of Customers on Wednesday} - \text{Number of Customers on Tuesday}}{\text{Difference in Days}}
\]

From the provided data:

- Number of customers on Tuesday = 353
- Number of customers on Wednesday = 350

Now, plug in the values:

\[
\text{Rate of Change} = \frac{350 - 353}{1} = \frac{-3}{1} = -3
\]

Therefore, the rate of change in the number of customers from Tuesday to Wednesday is \(-3\) customers per day, indicating a decrease of 3 customers.
