please put all of the necessary information and computations for better understanding.

1. The Fairy Company purchased a site for limestone quarry for P 100,000 on January 2, 2020. It estimates that the quarry will yield 400,000 tons of limestone. It estimates that its retirement obligation has a fair value of P 20,000 after which the land can be sold for P 10,000. In 2020, 80,000 tons were quarried and 60,000 tons sold. Cost of production (excluding depletion) are P4 per ton. Required: a. Compute the depletion cost per ton. b. Compute the total cost of inventory at December 31, 2020. c. Compute the total cost of goods sold for 2020. 2. Cooler Company acquired a tract of land containing an extractable natural resource. Cooler is required by the purchase contract to restore the land to a condition suitable for recreational use after it has extracted the natural resource. Geological surveys estimate that the recoverable reserves will be 5,000,000 tons and that the land will have of P1,000,000 after restoration. Relevant cost information as follows: Land P 9,000,000 Estimated restoration costs 1,500,000 If Cooler maintains no inventories of extracted material, what should be the depletion expense per ton of extracted material
