y=80x+16 with x representing the amount of hours rented.
Slope-intercept form is:
y=mx+b
In this case, y represents the total cost. m represents the amount per hour, x represents the amount of time, and b represents the number you add.
You would plug in the information you have (m=80 as it is $80 per hour; b=16 as it is added to the final sum):
y=80x+16

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
