The financial advantage of purchasing the parts from the outside supplier would be $50,400.
The financial advantage (disadvantage) of purchasing the parts from the outside supplier can be calculated by comparing the total cost of producing the parts internally versus purchasing them from the supplier.
If the company produces the parts internally, the unit product cost is $20. However, if they purchase the parts from the supplier, the cost per unit is $13.
Since the company needs 7,200 parts, the total cost of producing the parts internally would be 7,200 * $20 = $144,000. On the other hand, purchasing the parts from the supplier would cost 7,200 * $13 = $93,600.
Therefore, the financial advantage of purchasing the parts from the outside supplier would be $144,000 - $93,600 = $50,400.
