Where "k" is the constant of proportionality.
We know that Maddy assume that the relation between the volume and the weight is proportional.
Then, let be "V" the volume in liters and "w" the weight in kilograms.
We can write the following equation:
So, if the boat of 555 liters weights 7.5 kilograms, we can find "k":
In order to solve the exercise, substitute the value of "k" and into the equation and solve for "w". Then:

<span>-10b - 35 + b < -b - 11
- 10b + b - 35 < -b - 11
-9b - 35 < -b - 11
- 9b + b < - 11 + 35
-8b < 24
