What Is the Annual Rate of Increase for the Price of Milk?

In summary, the "rate of increase problem" is a mathematical concept used to study the rate at which a quantity is increasing over time. It is calculated by dividing the change in quantity by the initial quantity and multiplying by 100. The rate of increase can be affected by factors such as market conditions, competition, and consumer behavior. By analyzing the rate of increase, predictions can be made about future trends and patterns. Real-world examples of this problem include population growth, stock prices, and changes in sales, among others.

As for any rate of change problem

[tex] r = \frac {\Delta P} {\Delta t}[/tex]

r is the rate of change, P is price, t is time.
