<PRE><B>Question 1039274</B>
A rancher with 750 ft of fencing wants to enclose a rectangular area and then divide it into four pens with fencing parallel to one side of the rectangle. 
(a) Find a function that models the total area of the four pens. 
--------------------
Let the width be &quot;w&quot;
Note: 2 of the sides are &quot;w&quot;
Each dividing segment is (750-2w)/5
Then depth of the rectangle is [150-(2/5)w
------
Total Area = w[(150-(2/5)w] = 150w - (2/5)w^2
