Use the table to determine the average rate of change from 3 to 6 storms.
3
0.09
0.26
0.51

Answer 1

The average rate of change in the price of bread from 3 to 6 storms is calculated as the change in price divided by the change in the number of storms, which is $0.09 per storm.

Step-by-step explanation:

To determine the average rate of change in the price of bread from 3 to 6 storms, we need to look at the change in price divided by the change in the number of storms predicted.

The price of bread when there are 3 storms is $2.41, and the price of bread when there are 6 storms is $2.68.

We find the change in price by subtracting the lower price from the higher price:

$2.68 - $2.41 = $0.27

We find the change in the number of storms by subtracting the lower number of storms from the higher number:

6 - 3 = 3 storms

Now, we calculate the average rate of change:

$0.27 / 3 storms = $0.09 per storm

Thus, the average rate of change in the price of bread from 3 to 6 storms is $0.09 per storm.
