Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

That was correct. Thank you!

Answer 5

All right !!!
