a) What was the average score when they initially took the test, t = 0? Round your answer to a whole percent, if necessary.

**Steve**, Wednesday, February 1, 2012 at 5:06pmwhat's the problem? Just plug in t=0:

S(0) = 68-20log(1) = 68 - 20(0) = 68

Although, as written, S(0) is not defined, since it is only for t>0, not t=0.

Looks like the scores keep going down and down. Is the problem written correctly?
