Students in a fifth-grade class were given an exam. During the next 2 years, the same students were retested several times. The average score was given by the model: f(t) = 83 – 13 log(t+1), 0≤ t ≤ 24 where t is the time in months. Round all answers to nearest tenth. a) What is the average score on the original exam? b) What was the average score after 6 months? c) What was the average score after 18 months?
