 For the next little section, we're going to actually be working off of running optimal numbers, trying to figure out what's the best combination to be working off of. One of the things we have to do is we have to enable our solver add-in. To do that, we actually head over to our file tab and go into our options. From here, we actually want to go into our add-ins and this is actually looking down below. You see that I have an inactive active application add-ins, solver add-in. From here, I will go ahead and say go. That's going to pull up all of the different options that I can work off of. The one I want to focus in on right now is just selecting solver and hitting OK. It will take a second, but as you notice, now all of a sudden in my data tab, I have the solver section.
