Answer:
The rate of change is $21.5 per hour
Step-by-step explanation:
The rate of change can be found using the formula: (y^2 - y^1)/(x^2 - x^1).
(the exponents refer to which number. Y^2 refers to the y-axis number of the second number given)
So fill in the blanks:
(430 - 215)/(20– 10)
Now do the math:
430 - 215 = 215, 20 - 10 = 10
(215)/10
Divide:
215/10 = 21.5
Therefore, 21.5 is the rate of change!
