Question

Susan 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 22 cents per yard. if after that purchase there was $7.30 left on the card, how many yards of ribbon did susan buy?

Answer 1

35 yards of ribbon

Explanation:

You can create the following equation:

.22x + $7.30 = $15

You can then simplify the equation to:

.22x = $7.70

Then you get

x = $7.70/.22

x = 35
