Futura Company purchases $69,000$ starters from a supplier at $$12\mathrm{.}40$ per unit that it installs in farm tractors. Due to a reduction in

output, the company now has enough idle capacity to produce the starters rather than buying them from the supplier. However, the

company's chief engineer is opposed to making the starters because the production cost per unit is $$13\mathrm{.}90,$ as shown below:

If Futura decides to make the starters, a supervisor would be hired $($at a salary of $$138,000)$ to oversee production. However, the

company has sufficient idle tools and machinery such that no new equipment would have to be purchased. The rent charge above is

based on space utilized in the plant. The total rent on the plant is $$89,000$ per period.

What is the financial advantage $($disadvantage$)$ of making the $69,000$ starters instead of buying them from an outside supplier?
