To write an equation relating the cost (c) and the number of beads (n) based on the given information, we can use the concept of unit rate.
The given information states that 12 cents is the cost for 15 beads.
If we divide the cost by the number of beads, we can find the cost per bead:
12 cents / 15 beads = 0.8 cents per bead
The cost per bead can also be written as 0.8n cents, where n represents the number of beads.
Therefore, the equation relating the cost (c) and the number of beads (n) is:
c = 0.8n
Please note that this equation assumes that the cost and number of beads have a linear relationship and the cost per bead remains constant.
