Question

It costs $15 to send 3 packages through a certain shipping company. Consider the number of packages per dollar

Answer 1

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
