Consider a resource allocation problem having the following data:

	Resource Usage Per Unit of Each Activity
Resource	1	2	Amount of Resource Available
1	1	2	10
2	1	3	12
Unit Profit	$2	$5

The objective is to determine the number of units of each activity to undertake so as to maximize the total profit.

While doing what-if analysis, you learn that the estimates of the unit profits are accurate only to within 50 percent. In other words, the ranges of likely values for these unit profits are $1 to $3 for activity 1 and $2.50 to $7.50 for activity 2.

Also check whether the optimal solution remains optimal if the unit profit for activity 1 still is $2 but the unit profit for activity 2 changes from $5 to $2.50. Does the optimal solution change?

From $5 to $7.50. Does the optimal solution change?
