Answer: $450,000
Step-by-step explanation:
It is shown that Nana Company does not have significant influence over Mama Company.
What this means is that Mama's retained earnings, incomes or dividends have no effect on the investment account of Nana in relation to their Mama investment.
The only relevant amount is the fair value of the Mama's stock that Nana owns.
= 10,000 * 45
= $450,000
