Lin got a $50 gift card to an online music store. She uses the gift card to buy an album for $9.99. She also wants to use the gift card to buy some songs. Each song costs $1.29. Which of these inequalities describes the situation, where n is the number of songs Lin wants to buy.
9.99+1.29n greater and equal to 50
9.99+1.29 less than and equal to 50
9.99-1.29n less than or equal to 50
9.99-1.29n greater than or equal to 50

b) 9.99 + 1.29n ≤ 50

Step-by-step explanation:

  I think,  this question is incomplete., may be there is typo. To complete the question, it's suppose to be like this  

a)9.99 + 1.29n ≥ 50

b)9.99 + 1.29n ≤ 50

c)9.99 − 1.29n  ≤ 50

d)9.99 − 1.29 n ≥ 50

well,  we have to figure out  the information given  

price of the album: $9.99

each song cost : $1.29

gift card: $50

number of songs : n

The answer  is b) 9.99 + 1.29n  ≤ 50 , because the sum of the price of the album ($9.99) and the songs ($1.29 n) must be less or equal to the value of the gift card ($50). Fore sure it 's correct

false
