Use MS Excel Solver to develop and solve a linear programming model for this problem.

Consider the following linear programming problem:

Min $5x+4Y$

$s.t.3x+Y18$

$x+2Y14$

$3x,15$

$x,Y0$

Answer in one $(1)$ decimal point.

a$.$ The final value of the objective function is: type your answer.

b$.$ The final value of the decision variable $x$ is: type your answer...

c$.$ Constraint $1$: $3x+Y18,$ the status shows as

d$.$ If you have to increase the right$-$hand$-$side value for one of the constraints that affects the optimal point, which constraint is best candidate for this scenario? choose your answer...
