The Dormir Company uses an activity-based costing system to account for its process of manufacturing camping tents. Each tent has $140 of direct materials, includes 15 parts, and requires 3 hours of machine time. Information on conversion costs, manufacturing activities, and cost drivers is listed below. Cost Per Manufacturing Activity Cost Driver Unit Material handling Number of parts $ 3.00 Sewing Machine hours 20.00 Assembling Number of parts 1.00 Testing Number of finished units 8.00 The total manufacturing cost per tent is:

$268 Total manufacturing cost: $140 + (15 x $3) + (3 x $20) + (15 x $1) + 8 = $268
