If 13 key chains cost 38.35 what is the cost of 20 key chains

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
