= $0.08
Therefore, the expectation of the contest will be $0.08.
we are given
we can use average rate of change formula from t=a to t=b
Here, we are given from t=1 to t=4
so, we will get formula as
now, we can plug values
now, we can simplify it
the average rate of change in the number of acres cleared for farming between t = 1 and t = 4 is 10 acres/ month.............Answer
