A325 Summer 2013 Problem Set #1 SHOW FORMULAS USED AND ALL WORK FOR MAXIMUM CREDIT - 20 points total...

I am having trouble with Problem 1, part a. I am not sure what all to include into prime costs. I know it is total prime costs = direct materials + direct labor but do not know what all I should include (ex. direct manufacturing labor fringe benefits, overtime premium, etc.) Can you help with part (a) please, prime costs, total manufacturing OH, and total selling and administrative?
