8. Your final exam grade (E) is directly proportional to the amount of time you spend studying for it (in hours) (T), and inversely proportional to the square root of

the amount of screen time that you watch (in hours) the week before you take the exam (W). a. If a person earned a 90% for their final exam grade, and they studied 15 hours for it, and watched 36 hours of screen time the week before the exam, use this information to find the constant of proportionality. b. Once you have the constant of proportionality, predict a person's exam grade, assuming they studied for 8 hours, and watched 25 hours of screen time the week before their exam.
