Answer: There will 486 bacteria in 31 hours.

Step-by-step explanation:

The population decay in bacteria is exponential.

Exponential function : $y=Ab^x$ , where A = initial population, b multiplication decay factor, t= time:

As per given:

Initial population: $A=120,000$

After 36 hours, population = $120000(b^{36})=200$

Divide both sides by 120,000 we get

$b^{36}= 0.00167$

Taking natural log on both sides , we get

$36\ln b=\ln 0.00167\\\\\Rightarrow\ b=e^{\left(\frac{\ln0.00167}{36}\right)}=0.83724629\approx0.8372$

At x= 31,

$y=120000(0.8372)^{31}=120000\times0.00405234\approx486$

Hence, there will 486 bacteria in 31 hours.
