Answer:
C.$300,000
Explanation:
Data provided in the question
Number of gallons required = 10,000
Cost of supplies on hand = $300,000
Not paid amount = $100,000
Earning from services = $800,000
So by considering the above information, the supplies assets should be recorded at cost or net realizable value whichever is lower
So in this case, the supplies value is $300,000 and the same is to be recorded in the financial statements
