Answer: $1,175,000
Explanation:
Cost of ending inventory December 31, 2021;
= December 2019 ending inventory + {(Inventory at 2021 price/2021 index * 2019 index) - December 2019 ending inventory} * 2021 index / 2019 index
= 1,100,000 + {(1,450,000/125 * 100) - 1,100,000} * 125/100
= 1,100,000 + 75,000
= $1,175,000
