A fast food offers a special for $9.99. The customer can choose from

3
3 types of main courses,
2
2 types of sides,
5
5 drinks, and
4
4 sauces. Assuming you will pick exactly one of each how many different possibilities are there?

To find the total number of different possibilities, we need to multiply the number of options for each category.

For the main course, we have 3 options.
For the side, we have 2 options.
For the drink, we have 5 options.
For the sauce, we have 4 options.

To calculate the total number of possibilities, we multiply these numbers together:

3 * 2 * 5 * 4 = 120.

Therefore, there are 120 different possibilities in total.
