Using the combination formula, and considering that the list has 6 ingredients, it is found that 20 groups of 3 different ingredients can go on a taco.
The order in which the ingredients are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.
<h3>Combination formula:
</h3>
is the number of different combinations of x objects from a set of n elements, given by:
In this problem, 3 ingredients are chosen from a set of 6, hence:
![C_{6,3} = \frac{6!}{3!3!} = 20](https://tex.z-dn.net/?f=C_%7B6%2C3%7D%20%3D%20%5Cfrac%7B6%21%7D%7B3%213%21%7D%20%3D%2020)
20 groups of 3 different ingredients can go on a taco.

This is an example of an exponential decay problem.
The basic format of the equation is:
![y=ab x^{123} x](https://tex.z-dn.net/?f=y%3Dab%20x%5E%7B123%7D%20x)
In this problem, the starting amount is 100. The rate is 0.5 because it is being cut in half every 330 days.
Answer:
105 11/12
Step-by-step explanation:
With mixed numbers you can also write them as functions so 5 11/12 could also be written as 5+11/12.
Once you have rewritten the mixed number it's simply a matter of addition: 100+5+11/12
