I'm struggling on solving question 3 and then figuring how to make a infographic that walk people through the problem an then figuring how to explain logarithms

Problem 3 A dog takes 400mg of Rimadyl. Each hour, the amount of Rimadyl in the dog's system decreases by about 29%. How much Rimadyl is left in the system after 6 hours? Initial post, due 3am ET Thursday: Part 1: After solving your chosen problem, create an infographic that walks someone through your example problem and explains why you chose that problem. . What type of function is represented in the problem? . What method did you use to solve your problem? . What formula, if any, did you use? . How does it apply to your field of study? . How might this example apply to other situations? Part 2: Your infographic must also explain logarithms, how to use and interpret a logarithmic scale, and any information needed to understand your example problem. Please also provide the following information: . What is the general formula for logarithms? . What notation is used? . How are logarithms used? What are the findings or analysis? Why does the example use or show up in this scale
