Question

Salma got a prepaid debit card with $20 on it. For her first purchase with the card, she bought some bulk ribbon at a craft

store. The price of the ribbon was 7 cents per yard. If after that purchase there was $18.46 left on the card, how many yards of
ribbon did Salma buy?

Answer 1

22 yards

Explanation:

Let x equal the number of yards of ribbon at $.07 per yard:

$18.46 + 0.07x = $20.00

Solve for x

Subtract $18.46 from both sides

0.07x = $1.54

Divide both sides by .07

x = 22
