Answer:
A) The equation is y = 5/6x
B) The constant of proportionality is 5/6
Step-by-step explanation:
If it cost $5 to send 6 packages, you can write this as 5 over 6 (5/6), as 5 representing y and 6 as x. So the first equation is k = y/x, so in this case it can be written as k = 5/6. Then it can be written as y = kx, so in this case it will be y = 5/6x
