Jon has a $21.61 balance on a gift card that can be used to purchase online music. He bought some songs that each cost $1.29. Now he has $10 left. How many songs did Jon purchase? Write and solve a two-step equation.

• 1.29d - 21.61 = 10, d = 24.5 songs

• 21.61 - 1.29d = 10, d = 9 songs

• 21.61 - 1.29d = 10, d = -9 songs

• 1.29d - 21.61 = 10, d = 9 songs
