Final answer:
Chloe does not have enough money on her gift card to buy a $12 digital movie after purchasing 10 music downloads for $0.89 each, as she only has $11.10 remaining on her card.
Step-by-step explanation:
To answer whether Chloe has enough money on her gift card to buy a digital movie after purchasing music downloads, we need to calculate the total cost of the downloads and subtract that from her gift card balance. Chloe has a $20 gift card and buys 10 music downloads at $0.89 each.
To represent the situation with an equation where d is the amount left on the gift card after m music downloads, we can use the equation d = 20 - 0.89m. Plugging in the number of downloads Chloe purchases, which is 10, we get d = 20 - 0.89(10) or d = 20 - 8.90, which equals d = 11.10.
Since Chloe wants to purchase a $12 digital movie, we can see that $11.10 is not enough to cover the cost of the movie. Therefore, Chloe does not have enough money left on her gift card to buy the digital movie.
