Detailed Answer
Answer (B) is correct.
Denver Corp.’s purchase of 30% of Eagle presumably allows it to
exercise significant influence. Hence, it should apply the equity method.
The investor’s share of the investee’s income is a function of the
percentage of ownership and the length of time the investment was held.
The income from this investment was therefore $18,000 [$120,000 ×
30% × (6 months ÷ 12 months)].
