Step 1
We are given that students we re-tested on College Algebra, on a monthly basis, after final exam, starting in May.
The average score (x) for the class is given by the human memory model, x=8615log(t+1),
where t is the time in months after the final exam.
We are asked to find the average score 5 months after the final exam.
Step 2
Noe, to find the average score 5 months after the final exam, we substitute t=5 in the formula
x=8615log(t+1).
This gives us
x=8615log(5+1),
x=8611.672
x=74.328
