So what is the price of 1 bead?

anonymous · Answer

Let c = Cost of craft beads and let n equal number purchased and let k equal the cost of each bead. 

Because the relationship is a direct one, the equation would be c = kn 

This direct relationship means that when one side increases, teh other side also increases. Likewise, when one decrease, the other also decreases. This means they are directly related.
