Delaney put a $720 item on layaway by making a down payment of 12% of the purchase price. how much does she have left to pay after making the down payment?

$633.60

Step-by-step explanation:

Purchase price for the item = $720

Down payment = 12% of purchase price

Amount to be paid = (100% - 12%) of purchase price

                                = 88% of $720

                                = 0.88 × $720

                                = $633.60

Delaney has $633.60 left to pay after making the down payment.

the solution is h=10 because you add 9 to each side of the equation.
