Answer:
Total cost= $877,500
Explanation:
<u> First, we need to calculate the unitary variable cost:</u>
Unitary variable cost= 135,000 / 30,000= $4.5
Unitary variable cost= 180,000 / 40,000= $4.5
Unitary variable cost= 225,000 / 50,000= $4.5
<u>Now, the total cost for 35,000 hours:</u>
Total cost= Unitary variable cost*total number of hours + fixed costs
Total cost= 4.5*35,000 + 720,000
Total cost= $877,500
