Bacteria population increases by 9.8% per hour.
Population = (1.098)^hours
Solving this for time we get:<span>
</span><span>
</span><span>Time = log(ending amount / beginning amount) ÷ log (1 + rate)</span>
<span />
Since we must solve the problem for the population to double, we'll say
beginning amount = 100 and ending amount = 200
Time = log(200 / 100) ÷ log (1 + .098)
Time = log(2) ÷ log (1.098)
Time = 0.30102999566 / 0.040602340114
Time =
