Hooray! The first solution for this problem! So everyone, look at this and see, first, if you think it's right. Then think about how thoroughly explained it is. THEN think about how hard it is to describe solutions to problems like these even when you explain everything.
So what would make this easier to understand? I think there are two things (and no, I don't expect anyone to do all these things, I'm just using this hard work as an example):
One: make it clear which things are the answers
Two: maybe make a table or diagram to show results and even some of the logic
Finally, see how much she uses multiplication of fractions or percentages. If it's not obvious to you why this is important, you should hurry to figure it out!
