For the given LP formulation, find the optimal solution using excel solver. Max(Z) = 2000X1 + 1700X2 + 1200X3 Constraints : X1 + X2 + X3 <= 12 25X1 + 20X2 + 19X3 <= 280 X1,X2,X3 >= 0

Excel Solver gives the following solution:

Step-by-step explanation:

The objetive function, that is intended to maximize is

The constraints of the LP problem are:

Excel Solver gives the following solution:

The attached picture gives the configuration used for solver to solve this LP formulation.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
