The right answer is Option B.

Step-by-step explanation:

Let,

Number of songs = x

Price of 1 song = $0.99

Membership fee = $19.99

Total amount paid = $21.97

According to given statement;

0.99x+19.99=21.97

Subtracting 19.99 from both sides

$0.99x+19.99-19.99=21.97-19.99\\0.99x=1.98$

Dividing both sides by 0.99

$\frac{0.99x}{0.99}=\frac{1.98}{0.99}\\x=2$

Lauren bought 2 songs.

The right answer is Option B.
