Answer: There will 486 bacteria in 31 hours.
Step-by-step explanation:
The population decay in bacteria is exponential.
Exponential function :
, where A = initial population, b multiplication decay factor, t= time:
As per given:
Initial population: 
After 36 hours, population = 
Divide both sides by 120,000 we get

Taking natural log on both sides , we get

At x= 31,

Hence, there will 486 bacteria in 31 hours.
