Question

Laqueta has a $50 gift card for an online music store. Each song costs s dollars. Write an algebraic expression that represent the amount left on the card after Laqueta buys 7 songs

Answer 1

`x = 50-7s`

Explanation:

Remember, we are not told the cost of each song; meaning it will be represented by 's'.

x represents the amount left on the card

7 the number of songs Laqueta wants to buy

Assuming the cost of each song is $0.9 then the formula could be applied this way

`x = 50-7 (0.9)`

`x = 50-6.3`

`x = 43.7` or $43.7
