Han Products manufactures 21,000 units of part S-6 each year for use on its production line. At this level of activity, the cost per unit for part S-6 is:

Direct materials	$	4.20
Direct labor		6.00
Variable manufacturing overhead		3.60
Fixed manufacturing overhead		12.00
Total cost per part	$	25.80

An outside supplier has offered to sell 21,000 units of part S-6 each year to Han Products for $47.50 per part. If Han Products accepts this offer, the facilities now being used to manufacture part S-6 could be rented to another company at an annual rental of $632,700. However, Han Products has determined that two-thirds of the fixed manufacturing overhead being applied to part S-6 would continue even if part S-6 were purchased from the outside supplier.

Required:

a.	Calculate the per unit and total relevant cost for buying and making the product?(Round your "per unit" answers to 2 decimal places.)

b.	How much will profits increase or decrease if the outside supplier?s offer is accepted?
