Question

The price of bread has been increasing over the last month. Brian believes there is a positive correlation between the number of predicted storms and the price of bread.


Number of Storms Predicted Bread Price
1 $2.30
3 $2.41
4 $2.50
6 $2.68
7 $2.81


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

Answer 1

Answer: Second Option

$m=0.09$

Step-by-step explanation:

The formula for calculating the average rate of change between two values of x ($x_1$ and $x_2$) is:

$m=\frac{f(x_2)-f(x_1)}{x_2-x_1}$

$f (x_1)$ and $f (x_2)$ are the values of the function when $x = x_1$ and $x = x_2$

In this case

$x_1=3\\x_2=6$

Observe that when $x=3$, $f(x) =2.41$ and when $x=6$, $f(x)=2.68$

Finally the average rate of change from 3 to 6 storms is:

$m=\frac{2.68-2.41}{6-3}$

$m=0.09$
