11. Assembly for Acrylic Clock Join the base and the background by press fitting Insert battery into clock insert Place clock insert into clock housing

12. Bill of Materials Acrylic Sheet (48 x 96)inch = $215 Clock Insert = $5.90 (30 count) = $177 Batteries = $0.55 (30 count) = $16.50

13. Cost Analysis Break even point – 22 clocks –Selling Price of $50 Want to produce 8 extra for the 3 group members and 5 professors.
