Question

the manager of a deli counted the number of sandwiches sold each day. sandwich sales day sandwiches sold tuesday 53 wednesday 68 thursday 90 friday 84 saturday 58 according to the table, what was the rate of change between tuesday and wednesday? sandwiches per day

Explanation:

Step1: Identify the formula for rate of change

The formula for rate of change is $\frac{\text{Change in value}}{\text{Change in time}}$. Here, the change in value is the change in the number of sandwiches sold, and the change in time is 1 day (from Tuesday to Wednesday).

Step2: Calculate the change in the number of sandwiches sold

The number of sandwiches sold on Tuesday is 53 and on Wednesday is 68. The change in the number of sandwiches sold is $68 - 53$.
$$68-53 = 15$$

Step3: Calculate the rate of change

Since the change in time is 1 day, the rate of change is $\frac{15}{1}$.

Answer:

15
