How would I create a formula for the following problem if the food supply growth rate has doubled? The food supply is represented in millions and the food growth rate is about 1.92

Malthustan currently produces enough food to feed 12 million people, and is increasing its food
supply to feed an additional 160,000 people per year. In each of the six scenarios described below,
determine whether Malthustan will ever begin to experience food shortages.
