How to view the sensitivity analysis of the objective function in ILOG CPLEX Optimization Studio

Question

Here is my code below

     *********************************************/
dvar float+ x; /* daily quantity of t-shirts*/
dvar float+ y; /* daily quantity of shorts */


maximize 6*x + 10*y; /* maximize the daily profit from t-shirts and shorts*/

subject to{
20/60*x + 10/60*y <=176; /* cutting department labour constraint*/
20/60*x + 50/60*y <=400; /* sewing department labour constraint*/
10/60*x + 10/60*y <= 96; /* packaging department labour constraint*/
x >= 100; /* minimum daily demand for t-shirts*/
}

i want to find a range for unit profit where optimal solution doesn't change by finding the co-efficiency of objective function. thanks.
