Royal Company manufactures 26,000 units of part R-3 each year for use on its production line. At this level of activity, the cost per unit for
part R-3 is: Direct material – $4.90 ; Direct Labor – $7 ; Varialble Manufacturing overhead – $ 3.00 ; Fixed Manufacturing overhead – $15 ;
total cost per part – $ 29.90.

An outside supplier has offered to sell 26,000 units of part R-3 each year to Royal Company for $49.50 per part. If Royal
Company accepts this offer, the facilities now being used to manufacture part R-3 could be rented to another company at an annual rental of
$780,600. However, Royal Company has determined that $10 of the fixed manufacturing overhead being applied to part R-3 would continue even if
part R-3 were purchased from the outside supplier.

Total Relevant cost of making 26000 units = $1,298,000

Total relevant cost of buying the product (26000 units) = $1,287,000

What is the oppoutunity cost of making instead of buying?

How much would the profit increase by if the outside suppliers offer is accepted ?
