Answer in whole number.

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

b$.$ The final value of the decision variable $Y$ is

c$.$ Constraint $3$:$5Y15,$ the status shows as This is called

a variable.

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?
