It costs $15 to send 3 packages through a certain shipping company. Consider the number of packages per dollar a. Find the constant of proportionality for this situation. b. Write an equation to represent the relationship.
Let’s find the unit rate of the problem If we divide both $15 and 3 by 3 we get $5 and 1. That means every package costs $5, so the COP or k =5 b. Using 5 as the k in y=kx, the equation is y=5x
