Question

Kaitlin got a prepaid debit card with $30 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 16 cents per yard. If after that purchase there was $27.28 left on the card, how many yards of ribbon did Kaitlin buy?

Answer 1

`(17)/(100)`

Explanation:

(30 - 27.28) ÷ 16

`(2.72)/(16)` multiple both the numerator and denominator

`(272)/(1600)` =
`(17)/(100)` = 0.17

Answer 2

43.52 yards of ribbon

Explanation:

First you want to subtract $30 - $27.28 = $2.72 to get the missing amount,

Now you do $2.72 x $0.16 = 43.52 yards

$0.16 was how much each yard costs
