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

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

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