Chapter 8.7, Problem 44STP

To determine

To state the represent of slope.

Answer to Problem 44STP

Slope represent the cost of each hour

Explanation of Solution

Given information: The cost of renting a cotton candy machine is $\$30$ plus $\$5$ for each hour. The total cost of renting of cotton candy machine is represented by $C\left(h\right)=5h+30$ , where $h$ is number of hours.

Formula Used:

Slope intercept form of line is $y=mx+c$ , where

  $m=$ Slope of graph of equation

  $c=$ y-intercept of graph of equation

Calculation:

Given the total cost of renting of cotton candy machine is represented by $C\left(h\right)=5h+30$ , where $h$ is number of hours.

Equation of line is

  $C\left(h\right)=5h+30$

Comparing the above equation to slope intercept form of line $y=mx+c$ , slope and Y-intercept are

  $\begin{array}{l}m=5\\ c=30\end{array}$

Here, slope means cost of each hour

Hence, correct option is B
