if you want to find this one out do 38.35 divided by 13 because you want to divide the price by how many and that will give how much 1 cost then you times that by 20 and you'll get your answer so 38.35/13=2.95 so you price if 1 key chain is 2.95. then you multiply that by 20 and that would give you 20 key chains and the price, sooo...... 20 times 2.95=59 so the price of 20 key chains is 59 bucks
