Answer:
The overhead cost per unit of product A1 under activity based costing is $13.53
Step-by-step explanation:
Activity 1 allocated to product A1 line: $63,000*2,700/9,000= $18,900
Activity 2 allocated to product A1 line: $78,000*3,740/10,000= $29,172
Activity 3 allocated to product A1 line: $110,000*8,700/11,000= $87,000
Total overhead allocated to product A1= $18,900+$29,172+$87,000= $135,072
Overhead per unit of product A1: 135,072/9,980= $13.53
