Alejandra's Tapas Bar offers a menu consisting of 9 savory and 5 sweet dishes. You can also get a mix-and-match plate consisting of two different dishes on the menu. How many different mix-and-match plates can you get in total?

9 times 8 = 72 ways.

But since there is a mix and match you'd need to divide 2.

72 divided by 2 is 36, the answer!

See final answer posted here:

14 total dishes to choose from

14 * 13  / 2 = 91  different  mix/match plates of two items (if the two item must be different )
