Answer:
None of the above options are correct
Depletion amount in 2019 = $52.480
Explanation:
The Cost of Quarry (Depletion Base ) = $164000
Estimated Salable Rock (Units Extracted) = 20000 tons
Depletion Rate = Depletion Base /Units Extracted
Depletion Rate for 2018 = 164000/ 20000 = $8.2/ton
Units Extracted in 2018 = 4000 tons
Depletion amount in 2018 = Depletion Rate for 2018 *Units Extracted in 2018
Depletion amount in 2018 = $(8.2*4000) = $32800
In 2019
Depletion Base in 2019 = The Cost of Quarry - Depletion amount in 2018 = 164000-32800 = $131200
Estimated Salable Rock in 2019 (Units Extracted) = 20000 tons
Depletion Rate for 2019 = 131200/ 20000 = $6.56/ton
Units Extracted in 2019 = 8000 tons
Depletion amount in 2019 = $(6.56*8000) = $52480
