There are 70,000 bacteria present in a culture. an antibiotic is introduced to the culture and the number of bacteria is reduced by half every 4 hours. what will be the population in 24 hours

1,094 bacteria

There are 6 periods of 4 hours in 24 hours, so the population will be multiplied by 1/2 6 times. That is, it will be multiplied by (1/2)^6 = 1/64.

The population then will be ...

... 70,000/64 ≈ 1094
