You have made two of the exact same necklaces that cost you a total of $15 in supplies. You have chosen to mark up the price by 15%. How much will each necklace be sold at and how much will you make in profit for each?
$15 / 2 = $7.50 - the cost of one necklace.
$7.50 x 1.15 =$8.63 - sale price of each necklace after 15% markup.
$8.63 - $7.50 =$1.13 - profit on each necklace.
