A new teaching method to teach vocabulary to sixth-graders involves having students work in groups on an assignment to learn new words. After the lesson was completed. the students were tested at 1-month intervals. The average score for the class S(t) can be modeled by S ( t ) = 94 − 18 ln ( t + 1 ) where t is the time in months after completing the assignment. If the average score is 65, how many months had passed since the students completed the assignment? Round to the nearest month.
