Beads for sale: 12cents for 15. Write an equation relating the cost (c) and the number of beads (n) for the beads.
12c+n=15
n=3
n=3 i think
c=1 and n=3

To find the equation relating the cost (c) and the number of beads (n) for the beads, we need to determine the cost per bead. We are given that 15 beads cost 12 cents.
First, let's find the cost per bead:
Cost per bead = Cost / Number of beads
Cost per bead = 12 cents / 15 beads
Now, we can express the cost per bead in terms of c and n:
Cost per bead = c / n
Equating the two expressions for the cost per bead, we get the equation relating the cost (c) and the number of beads (n):
c / n = 12 cents / 15 beads
Therefore, the equation relating the cost (c) and the number of beads (n) is:
c / n = 12/15 or c = (12n) / 15
