Step-by-step explanation:
Manufacturing overhead for department 1 = $3,141,500
Direct labor hours for department 1 = 167,000
Direct machine hours for department 1 = 267,000
Manufacturing overhead for department 2 = $1,571,000
Direct labor hours for department 2 = 267,000
Direct machine hours for department 2 = 192,000
Total manufacturing overhead = $3,141,500 + $1,571,000 = $4,712,500
Total direct labor hours = 167,000 + 267,000 = 434,000
Total machine hours = 267,000 + 192,000 = 459,000
Pre- determined overhead rate per MH
=
![(total\ manufacturing\ overhead)/(total\ machine\ hours)](https://img.qammunity.org/2020/formulas/business/high-school/jckaa4ci6j7uiva20k3lw3z0mhojqckp2s.png)
=
![(4,712,500)/(459,000)](https://img.qammunity.org/2020/formulas/business/high-school/33t5c6ssd2shk8iqkawq918box2jmstv0t.png)
= $10.27 per MH
Overhead rate per unit
= Pre-determined overhead rate per MH x Machine Hours required per unit
= $10.27 per MH x 0.70 MHs per unit
= $7.186 per unit
