Answer:
E. $560,000
Step-by-step explanation:
Balance of Long term Investment
= Value of Investment - Pre Acquisition Dividend ($100,000*40%) + Share of Net Income ($500,000*40%)
= $400,000 - $40,000 + $200,000
= $560,000
Therefore, The balance in Madison Corporation's Long-Term Investment-Jay Corporation account as of December 31 should be $560,000.
