Final answer:
Taylor has $21.00 left after buying a $9.00 picture frame from her $30.00 gift card. Each journal costs $3.00, so she can afford to buy 7 journals.
Step-by-step explanation:
Taylor started with a $30.00 gift card. She spent a part of it and bought a picture frame which costs $9.00. To find out the remaining amount on the gift card, we subtract the cost of the picture frame from the total amount on the card: $30.00 - $9.00 = $21.00. Now she wants to buy journals which each cost $3.00. To find out how many journals she can buy, we divide the remaining amount on the card by the cost of one journal: $21.00 / $3.00. The result is 7, so she can buy 7 journals without going over the card's limit.
