Question

Karen got a prepaid debit card with $15 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 24 cents per yard. If after that purchase there was $8.28 left on the card, how many yards of ribbon did Karen buy?

Answer 1

Karen bought 28 yards of ribbon using her prepaid debit card. We calculated this by subtracting the remaining balance from the initial balance and then dividing by the price per yard of the ribbon.

Step-by-step explanation:

To determine how many yards of ribbon Karen bought, we need to calculate the difference between the initial amount on the card and the remaining balance after her purchase. The initial prepaid debit card balance was $15.00, and after purchasing the ribbon, Karen had $8.28 left.

We can set up an equation to solve for the number of yards (y) of ribbon bought:

Initial balance - Price per yard × y = Remaining balance

15.00 - 0.24y = 8.28

Subtracting the remaining balance from the initial balance, we have:

15.00 - 8.28 = 0.24y

6.72 = 0.24y

To find the number of yards, we divide both sides of the equation by the price per yard:

y = 6.72 / 0.24

y = 28

Therefore, Karen bought 28 yards of ribbon.
