The cost of each song is Rs 1.75
<h3>How to solve algebra word problems?</h3>
Let the variable representing the cost of 1 song be x.
Now, since she was given a $50 gift card to a music downloading app. She purchased 18 songs from the app that all cost the same amount each. If she has $18.50 remaining on her gift card. Thus, we can express this as;
50 - 18x = 18.50
-18x = 18.50 - 50
-18x = -31.5
x = -31.5/-18
x = 1.75
Therefore, the cost of each song is Rs 1.75
