Question

the graph shows the cost to bowl at bowl - o - rama. the lines represent the total cost on different days of the week, y, as a function of time in hours, x. what is the hourly cost to bowl from friday to sunday? find the rate of change. rate of change from fri - sun: blank (with a graph showing total cost ($) on y - axis and time (hours) on x - axis, two lines: one for fri - sun starting at (0,2) and one for mon - thurs starting at (0,0), and a number pad at the bottom left)

Explanation:

Step1: Select two points on the Fri - Sun line

Let's take the points \((0,0)\) and \((2,8)\)

Step2: Use the rate of change formula \(m=\frac{y_2 - y_1}{x_2 - x_1}\)

Here, \(x_1 = 0,y_1=0,x_2 = 2,y_2 = 8\)
\(m=\frac{8 - 0}{2-0}=\frac{8}{2}\)

Answer:

\(4\)
