Ответ:
2nd Option is correct.
Step-by-step explanation:
Given:
Renata has $20 in gift card.
She bought 16 songs.
After purchase Balance in gift card = $0
⇒ Cost of 16 songs = $20
⇒ Cost of 1 song = 20/16 = $ 1.25
let x represent number of songs purchased and y represent balance on her gift card.
So, Cost of x songs = 1.25 × x = 1.25x
And Balance = 20 - 1.25 x
Thus, Required equation representing relationship between balance on gift card and number of song purchased.
y = 20 - 1.25x
1.25x + y = 20
If we multiply both sides of equation with 4, we get
5x + 4y = 80
Therefore, 2nd Option is correct.
