<human>:  Nancy and Rose are making bracelets, and there are eight beads in each bracelet. Nancy has 40 metal beads and 20 more pearl beads. Rose has 20 crystal beads and twice as many stone beads as crystal beads. How many bracelets can Nancy and Rose make?
<bot>: How many pearl beads does Nancy have? ** Nancy has 40 + 20 = <<40+20=60>>60 pearl beads.
How many beads does Nancy have? ** So, Nancy has a total of 40 + 60 = <<40+60=100>>100 beads.
How many stone beads does Rose have? ** Rose has 2 x 20 = <<2*20=40>>40 stone beads.
How many beads does Rose have? ** So, Rose has 20 + 40 = <<20+40=60>>60 beads.
How many beads do Nancy and Rose have altogether? ** Thus, Nancy and Rose have 100 + 60 = <<100+60=160>>160 beads altogether.
How many bracelets can Nancy and Rose make? ** Therefore, they can make 160/8 = <<160/8=20>>20 bracelets.
