The function C(x) = 25.50x + 50 models the total cost for a cleaning company to clean a house, where x is the number of hours it
vodomira [7]

Answer:

<em>The average rate of change is $25.5 per hour, option B.</em>

Step-by-step explanation:

<u>Average Rate of Change </u>

When we are explicitly given some function C(x), we sometimes need to know the rate of change of C when x goes from x=x_1 to x=x_2. It can be computed as the slope of a line .

\displaystyle m=\frac{C(x_2)-C(x_1)}{x_2-x_1}

The provided function is

C(x)=25.50x + 50

We are required to compute the average rate of change between the points

x_1=3\ ,\ x_2=9

Let's compute

C(3)=25.50(3) + 50=126.5

C(9)=25.50(9) + 50=279.5

\displaystyle m=\frac{279.5-126.5}{9-3}

\displaystyle m=\frac{153}{6}=25.5

The average rate of change is $25.5 per hour, option B.
