please show calculations.

X Corporation paid $16,200 for a 90% interest in Vivo Corporation on January 1, 2020, when Vivo's stockholders' equity consisted of $9,000 Capital Stock, APIC of $1,000, and $3,000 of Retained Earnings. The excess cost over book value was attributable to the trademark, which has not been impaired since the acquisition date. The following occurs: 1. X sells merchandise to Vivo at 120% of X's cost. In 2020, X's sales to Vivo were $4,800, of which half of the merchandise remained in Vivo's inventory on December 31, 2020. (The 2020 ending inventory was sold in 2021.) In 2021, X's sales to Vivo were $6,000 of which 60% remained in Vivo's inventory at December 31, 2021. At year-end 2021, Vivo owed X $5,000 for the inventory purchased during 2021. 2. X Corporation sold equipment with a book value of $2,000 and remaining useful life of four years and no salvage value to Vivo Corporation on January 1, 2021, for $2,800. Straight-line depreciation is used. 3. During 2021, Kodak sold to X land for $50,000 that had a book value of $20,000. X still owns the land on 12/31/21. Prepare the acquisition analysis as of the acquisition date. Compute the unamortized differential as of 1/1/2021. Please help me with the calculations. Thank you
