Ethan is shopping on the Internet. He is going to buy 10 songs for his brother as a gift, and some additional songs for himself. Each song costs $1.09, and Ethan can spend up to $20 in all. Which inequality can be solved for n, the number of additional songs Ethan can buy for himself?

Answer 1

The inequality that can be solved for n is:

$1.09 * (10 + n) ≤ $20

This inequality represents the total cost of the songs Ethan is buying for himself and his brother. The left side of the inequality represents the cost of the 10 songs for his brother plus the cost of the additional n songs for himself, while the right side represents the maximum amount of money Ethan can spend, which is $20. By solving this inequality for n, we can find the maximum number of additional songs Ethan can buy for himself.
