Answer:

exponential growth function

Step-by-step explanation:

When dealing with a constant rate of growth as a percentage form the only way to model such a situation would be with an exponential growth function. This is because the amount that it is growing by is changing every time period cycle because the total amount keeps growing since it is a percentage. The exponential growth function would be the following...

f(x) = a(1+r)^{x}

where

  • a = initial value
  • r = percentage of growth in decimal form
  • x = is the number of years

Explanation:

Let's look at the 3 sandwiches and 3 soups first and then expand the calculation. There are 9 ways I can have one of the sandwiches and 1 of the soups:

And so we can see that we multiply the number of sandwiches and the number of soups to get the total number of ways to get one of each.

The same works for more categories of choices, and so we multiply the 3 sandwiches, the 3 soups, 4 salads, and 2 drinks to get:
