Final answer:
Ithaca's unit depletion rate is $1.56 per ton. The total depletion for year 1 is $39,000.
Step-by-step explanation:
To find Ithaca's unit depletion rate, we need to subtract the estimated residual value from the purchase price and divide the result by the expected amount of minerals extracted.
The unit depletion rate is calculated as follows:
(Purchase Price - Residual Value) / Expected Amount of Minerals Extracted
Substituting the values, we get:
($1,500,000 - $250,000) / 800,000
Simplifying the calculation gives us the unit depletion rate of $1.56 per ton.
To find Ithaca's total depletion for year 1, we need to multiply the extraction (or consumption) rate by the number of tons extracted in year 1.
The total depletion for year 1 is calculated as follows:
Extraction Rate x Tons Extracted in Year 1
Substituting the values, we get:
$1.56 per ton x 25,000 tons
Calculating the result gives us a total depletion for year 1 of $39,000.
