Students in a zoology class took a final exam. They took equivalent forms of the exam at monthly intervals thereafter. After t months, the average score S(t), as a percentage, was found to be given by the following equation, where t20. Complete parts (a) through (e) below. S(t)=83-16 In (t+1), 0≤t≤80 a) What was the average score when they initially took the test? The average score was%. (Round to one decimal place as needed.)
