Because if we think about what number would be halfway between .8 and 1.1. Well I think that number would be .95, right? If there were equal amounts of each, it would make sense for the mixture to have .95. But that's not the case, so we're going to set up an average equation just like we did in the previous video and let's see what we can do here. We're going to fill in the same things. It's going to equal our average, which in…
