Question

At an online bookstore, Alicia downloads 3 books for $9 each and 2 magazines for $4 each. She uses a $50 gift card to pay for the books. Write an expression that shows how she can figure out how much money is left on the card after making the purchases.

Answer 1

Answer:

$15

Step-by-step explanation:

So first we see that alicia buys 3 books for $9 and that would be 27 because 3x9=27. Now we also see that she bought 2 magazines for $4 and that would be 8 because we are multiplying 4x2. Now we add 27 and 8 which would give us 35. She uses a $50 card to make the purchase. We subtract, 50-35 and we would get 15. So alicia has $15 left on the card.
