864/8 gives you 108. There are 108 beads on each necklace. So for 15 necklaces, multiply 108 and 15. There are 1,620 beads in 15 necklaces.

Step-by-step explanation:
To find the right answer, do her work in reverse
37 times 2 = 74
74 + 6 = 80
Barbara had started with the number 80
Now do the work the way the teacher asked her to do it
80 - 2 = 78
78 / 6 = 13
Hope this helps!
