A baby blue whale weighed 5520 pounds at birth. After two days, the baby weighed 5710. After 14 days, the baby weighed 8180 poun
Aleonysh [2.5K]

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.

5710-5520=190

Now we will find difference of weights after 14 days and at birth. We will divide the difference by 14.

\frac{8180-5520}{14}

\frac{2660}{14}=190

We can see that weights are increasing at a constant rate of 190 pounds per day. Therefore, our constant of proportionality is 190.
