I'm trying to create a formula for the following problem that shows if the town managed to double its food supply rates (using linear or exponential form)but I'm not quite sure how...
A town currently produces enough food to feed 12 million people, and is increasing its food supply to feed an additional 160,000 people per year.Through a variety of means, they manage to increase its current food supply enough to feed an additional 2 million people.
This is what I have attempted:
y = 12000000 + 2(160000)x
= 12000000 + 320000x

Re: Growth rate formula
The formula as you have it represents what happens if you did double the rate of additional food supply coming in with a linear food model.
But the thing is you mention they need to feed an additional two million people (I'm guessing on top of the 12 million that already exist) but you haven't given a time frame for this event to take place (how many years for example).
If you want to solve for when you feed two million additional people this is different, but you need to specify what you want to find.
