Nancy has 40 + 20 = <<40+20=60>>60 pearl beads.

So, Nancy has a total of 40 + 60 = <<40+60=100>>100 beads.

Rose has 2 x 20 = <<2*20=40>>40 stone beads.

So, Rose has 20 + 40 = <<20+40=60>>60 beads.

Thus, Nancy and Rose have 100 + 60 = <<100+60=160>>160 beads altogether.

Therefore, they can make 160/8 = <<160/8=20>>20 bracelets.
