Question

Renate wins a $20 gift card to an online music site. After Renetta purchased 16 songs, the gift card has a remaining balance of zero dollars. Which equation represents the relationship between Y, the remaining balance on Manetta‘s gift card, and X, the number of songs purchased?

Answer 1

b. 5x + 4y = 80

Explanation:

Let us assume the remaining balance left be Y

and, the number of songs purchased be X

Given that

Wins a gift card of $20

And, the songs purchased is 16

Now if we take the fraction

= 20 ÷ 16

= 5 ÷ 4

So if we reverse this fraction

So it could be 5x and 4y

And, the amount that would come is

= $20 × 16 ÷ 4

= 80

So, the equation is 5x + 4y = 80

Hence, the correct option is b.
