a.
To find: A model for the value of van after
a.

Answer to Problem 71E
Explanation of Solution
Given information:
A van depreciates such that each year it is worth
Van cost originally at
Calculation:
From the given information, van depreciates such that each year it is worth
So, a model the value of van after
Hence, desired model equation is
b.
