First you would need to find out how many beads are needed for the bracelets.
215 beads per bracelet x 6 bracelets = 1290 beads
This tells us that to make all 6 bracelets, it will use up 1290 beads, now subtract that from your total number of beads.
1500-1290= 210
So Zoe will have 210 beads left over. Since this is a word problem, it is best to answer it in the same format:
Zoe will use 1290 beads to make 6 friendship bracelets. After all of the bracelets are made, she will have 210 beads left over.
hope this helps!
