Could someone help with this question.
Using the following information, compute the index at December 31, 2014, applying the double-extension method to a LIFO pool consisting of 25,500 units of product A and 10,350 units of product B. The base-year cost of product A is $10.2 and of product B is $37. The price at December 31, 2014, for product A is $21 and for product B is $45.6. (Round answer to 2 decimal places, e.g. 52.75.)
