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?


a.)4x + 5y = –100

b.) 5x + 4y = 80

c.)4x + 5y = 16

d.)5x + 4y = 20

Answer 1

Step-by-step explanation:

$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
