Han Products manufactures 18,000 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	$	5.00
Direct labor		6.00
Variable manufacturing overhead		2.80
Fixed manufacturing overhead		15.00
Total cost per part	$	28.80

An outside supplier has offered to sell 18,000 units of part S-6 each year to Han Products for $42.50 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 $431,600. 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 suppliers offer is accepted?
