If possible, I need help with the following:

Halsey Company manufactures 20,000 units of wheel sets for use in its annual production. Costs are as follows: direct materials are $40,000; direct labor is $50,000; variable overhead is $35,000; and fixed overhead is $70,000. Bowie Company has offered to sell Halsey 20,000 units of wheel sets for $10 per unit. If Halsey accepts the offer, some of the facilities presently used to manufacture wheel sets could be rented to a third party at an annual rental of $15,000. Additionally, $1.50 per unit of the fixed overhead applied to wheel sets would be totally eliminated.

I need assistance with, preparing an incremental analysis schedule to demonstrate if Halsey should accept Bowie's offer.
