Question

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?

Answer 1

y=1.25x

Explanation:

Since she bought 16 songs for 20 dollars, you divide $20 by 16 to get the answer of 20/16 which then simplifies into 1.25.
