Final answer:
To calculate the charge per hour for the Dozer, we need to determine the total costs associated with operating the machine for 1,400 hours per year. The owner of the Dozer should charge Ph979.46 per hour of use.
Step-by-step explanation:
To calculate the charge per hour for the Dozer, we need to determine the total costs associated with operating the machine for 1,400 hours per year.
First, we calculate the fuel, oil, grease, and minor maintenance cost:
(Ph580/operating hour) * 1,400 hours = Ph812,000
Next, we calculate the expected cost for replacing tires:
(Ph150,000/tire) * (2,800 use hours / 4,200 hours) = Ph100,000
Then, we determine the expected cost for major repair:
(Ph282,000/major repair) * (4,200 hours / 8,400 hours) = Ph141,000
Finally, we calculate the salvage value of the Dozer:
15% * Ph2,115,000 = Ph317,250
Adding up all the costs:
Ph812,000 + Ph100,000 + Ph141,000 + Ph317,250 = Ph1,370,250
Finally, we divide the total costs by the total operating hours per year:
Ph1,370,250 / 1,400 hours = Ph979.46
Therefore, the owner of the Dozer should charge Ph979.46 per hour of use.
