which of the following correctly models the situation and gives the average rate of change of elija's salary between 2012 and 2015?

answer is D

Step-by-step

S (t) = 24,400  * ln (t)

Rate of Change: $7,452.50 per year

Option D)

The average rate of change in Elija's salary between is $7452.50 per year.

Step-by-step explanation:

We are given the following in the question:

S(t) represent the Elija's salary.

S(t) can be obtained by multiplying starting annual salary, $24,400, by the natural logarithm of the product of 3.3 and the number of years since 2010, t.

Thus, we can write:

Average rate of change of function =

Putting b =  2015-2010 = 5, a = 2012-2010 = 2

We evaluate S(5) and S(2)

Average rate of change =

The average rate of change in Elija's salary is $7452.50 per year.
