n = 300*2^t We need to know t when n=36,000 36,000 / 300 = 2^t Taking logs of both sides log 36,000 - log 300 = t*log 2 4.5563025008 -2.4771212547 = t * 0.3010299957 2.079181246 = t * 0.3010299957 t=6.9068905956

That is what I got, but it told me I was wrong so I rounded to 6.91..

OpenStudy (wolf1728):

Okay maybe the answer is 6.9068905956 * 20 because the t is 20 minute time periods 138.1378119122 minutes

That was correct. Thank you!
