Remember the independent variable (
There are two points in this problem.
If the cost is increasing linearly, what is the growth rate? If the cost kept increasing in the same way, what will the milk cost
years from now?
Read the Math Notes box in Lesson 2.3.2 on finding equations of lines with 2 points.
Remember that slope is
Growth rate is $
If the cost is increasing exponentially, what is the growth rate? What will the milk cost in
