Question $4\mathrm{.}4$

Montreal Hardware Co$.$ is making a make$-$or$-$buy decision. The market feedback shows that the optimal price for this item is $\backslash (\backslash$$ $10\backslash )$ each. If the item is outsourced to Laval Hardware Co$,$ there is virtually no cost other than the $\backslash (\backslash$$ $6\backslash )$ per unit that they would pay Laval Hardware Co$.$ Internally, they have two choices. Process A requires an investment of $\backslash (\backslash$$ $120,000\backslash )$ for design and equipment, but it results in a $\backslash (\backslash$$ $4\backslash )$ per unit cost. Process $\backslash ($ B $\backslash )$ requires only a $\backslash (\backslash$$ $100,000\backslash )$ investment, but its per unit cost is $\backslash (\backslash$$ $5\backslash ).$ Regardless of whether the item is subcontracted or produced internally, there is a $\backslash (50\backslash \%\backslash )$ chance that they will sell $50,000$ units, and a $50\backslash \%$ chance that they will sell $100,000$ units. Draw the decision tree appropriate to the alternatives and outcomes stated. Using the decision tree and EMV, what is their best choice?
