$($b$)$ Which constraints are binding? What is your interpretation of these constraints in terms of the problem? $($Select all that apply.$)$

Constraint $1.$ All funds available are being utilized.

Constraint $2.$ The maximum permissible risk is being incurred.

Constraint $3.$ All available shares of U$.$S$.$ Oil are being purchased.

None of the constraints are binding.

$($c$)$ What are the dual values for the constraints? Interpret each. $($Round your answers to two decimal places.$)$

constraint $1$

Constraint $1$ has a dual value of $5.$ If an additional dollar is added to the available funds, the total annual return is predicted to increase by $$5.$

Constraint $1$ has a dual value of $0\mathrm{.}09.$ If an additional dollar is added to the available funds, the total annual return is predicted to increase by $$0\mathrm{.}09.$

Constraint $1$ has a dual value of $1\mathrm{.}33.$ If an additional dollar is added to the available funds, the total annual return is predicted to increase by $$1\mathrm{.}33.$

Constraint $1$ has a slack of $$200.$ Additional dollars added to the available funds will not improve the total annual return.

Constraint $1$ has a dual value of $3.$ If an additional dollar is added to the available funds, the total annual return is predicted to increase by $$3.$

constraint $2$

Constraint $2$ has a dual value of $5.$ If the risk index is increased by $1,$ the total annual return is predicted to increase by $$5.$

Constraint $2$ has a dual value of $0\mathrm{.}09.$ If the risk index is increased by $1,$ the total annual return is predicted to increase by $$0\mathrm{.}09.$

Constraint $2$ has a dual value of $1\mathrm{.}33.$ If the risk index is increased by $1,$ the total annual return is predicted to increase by $$1\mathrm{.}33.$

Constraint $2$ has a slack of $200.$ Allowing additional risk will not improve the total annual return.

Constraint $2$ has a dual value of $3.$ If the risk index is increased by $1,$ the total annual return is predicted to increase by $$3.$

constraint $3$

Constraint $3$ has a dual value of $5.$ If the maximum number of shares of U$.$S$.$ Oil is increased by $1,$ the total annual return is predicted to increase by $$5.$

Constraint $3$ has a dual value of $0\mathrm{.}09.$ If the maximum number of shares of U$.$S$.$ Oil is increased by $1,$ the total annual return is predicted to increase by $$0\mathrm{.}09.$

Constraint $3$ has a dual value of $1\mathrm{.}33.$ If the maximum number of shares of U$.$S$.$ Oil is increased by $1,$ the total annual return is predicted to increase by $$1\mathrm{.}33.$

Constraint $3$ has a slack of $200$ shares. Raising the maximum number of shares of U$.$S$.$ Oil will not improve the total annual return.
