1. The problem statement, all variables and given/known data Not sure if this is the right place to post this, but I'm really confused about what is going on here. Any sort of breakdown of the mathematical operations for each step would be incredibly helpful. 2. Relevant equations The ones given in the photo, not sure how to type them out in a readable way. 3. The attempt at a solution No clue, the answer is there but I can't make head or tail of it.
