Answer:
the overhead cost per unit is $675.91
Explanation:
The computation of the overhead applied to each unit is as follows:
Labour related ($507,394 ÷ $10,700 × $7,200) $341,424
Product testing ($9,464 ÷ 800 × 300) $3,549
Order size ($501,205 ÷ $5,900 × $3,100) $263,345
Total overhead $608,318
Divided by Units 900
Overhead cost per unit $675.91
hence, the overhead cost per unit is $675.91
Therefore the correct option is a.
