Let n represent the number of additional songs Ethan can buy for himself. The total cost of the songs for his brother is 10 * $1.09 = $<<10*1.09=10.9>>10.9.
The total cost of the additional songs for Ethan is n * $1.09.
The total cost of all the songs is $10.9 + n * $1.09 = $20.
Therefore, the inequality is 10.9 + 1.09n ≤ 20, which can be solved for n.
The answer is D. 10.9 + 1.09n ≤ 20.
