X axis is cc’s/mL. (Remember, one milliliter is one cubic centimeter – same thing)
Y axis is body weight in pounds (yay Imperial units!)
It’s a simple linear function. Plot two ordered pairs and connect with a straight edge, through the origin at (0,0).
In our case, the ordered pair (1, 110) is given on the label. We extrapolate (2, 220).
Easy-peasy, lemon squeezy.
