Now if, as based on the equality principle, both sides of Equation I (that shown in the preceding slide) are multiplied by the variable body weight, and divided by the variable food consumption, then the variable food concentration (on the left side of the equation) will be equal to the product of intake dosage times body weight divided by food consumption, as shown in Equation II here in this slide. Equation II also shows that if the variables intake dosage and body weight are further held constant, food concentration is simply inversely proportional to food consumption.
