Dan owns an ice cream shop and every sixth customer gets a free ice cream cone. Cones cost $2 each. If he sold $100 worth of cones, how many free ones did he give away?

How many cones did Dan sell? ** He sold 50 cones because 100 / 2 = <<100/2=50>>50
How many free cones did Dan give away? ** He gave away 10 cones because 50 / 5 = <<50/5=10>>10
