Question
Yoko got a prepaid debit card with 22.64 left on the card, how many yards of ribbon did Yoko buy?
Solution
To solve this problem, we need to find out how much money Yoko spent on the ribbon. We can do this by subtracting the remaining balance on the card from the original amount.
-
Subtract the remaining balance from the original amount: 22.64 = $7.36. This is the amount Yoko spent on the ribbon.
-
Now, we need to find out how many yards of ribbon Yoko bought. We know that the ribbon costs 16 cents per yard. To find out how many yards she bought, we divide the total amount spent by the cost per yard.
-
Convert the dollars spent into cents to match the unit of the cost per yard: $7.36 = 736 cents.
-
Divide the total cents spent by the cost per yard: 736 cents ÷ 16 cents/yard = 46 yards.
So, Yoko bought 46 yards of ribbon.
