Answer: $54,510,000
Step-by-step explanation:
The Investment at year end 2017 is;
= Opening Investment + Portion of Net Income - Unconfirmed profit on ending inventory - Dividends
Portion of Net Income
= 45% * 9,000,000
= $4,050,000
Unconfirmed profit on ending inventory
= (6,000,000 - ( 6,000,000/125%)) * 45%
= $540,000
Investment account at end of year = 55,000,000 + 4,050,000 - 540,000 - 4,000,000
= $54,510,000
