(d)
To Find: The reason why only two zeroes are considered in part (c).
(d)

Answer to Problem 55PPS
There are only two zeroes in part (c) as the items cannot be included in the negatives. The negative of the profit refer to the loss.
Explanation of Solution
There are only two zeroes in part (c) as the items cannot be included in the negatives. The negative of the profit refer to the loss.
Thus, the roots 2,6 are reasonable and
