Renata wins a $20 gift card to an online music site. After Renata purchases 16 songs, the gift card has a remaining balance of $0. Which equation represents the relationship between y, the remaining balance on Renata’s gift card, and x, the number of songs purchased?

Verified Answer :

$20 bought 16 songs
Therefore each song costs $20/16 = $5/4 = $1.25
So:
2 songs would cost 2 $1.25
3 songs would cost 3 * $1.25
...
x songs would cost x $1.25

Since Renata started with $20, then her balance (y) after buying x songs would be:

y = 20 - 1.25*x

The equation that represents the relationship between the remaining balance and the number of songs purchased is y = $20 - $1.25x.

What is the equation?

The first step is to determine the cost of one song.

Cost of one song = $20 / 16 = $1.25

Remaining balance = value of the gift card - (number of songs purchased x cost of one song)

y = $20 - $1.25x
