Answer:
$36 per purchase order; $20 per square foot
Explanation:
Factory expected cost:
= Cleaning factory + Providing utilities
= $35,000 + $77,000
= $112,000
Purchasing:
Activity overhead rate:

= $ 183,600 ÷ 5,100
= $36 per purchase order
Factory:
Activity overhead rate:
= Expected costs ÷ Expected amount of cost driver
