Answer:
Constant of proportionality is 190.
Step-by-step explanation:
To find proportionality constant we will find difference of weights after 2 days and at birth.
Now we will find difference of weights after 14 days and at birth. We will divide the difference by 14.
We can see that weights are increasing at a constant rate of 190 pounds per day. Therefore, our constant of proportionality is 190.
