Your baby brother has it you’re infection the doctor said there are probably 50,000,000 bacteria in his left ear. the penicillin the doctor prescribed will kill 7% of the bacteria every 6 hours. how many bacteria will be in your brother ear after 1 day? 

37402601

Step-by-step explanation:

24 hours in a day means that 4 7% are taken from 50 million.

7% of 50000000 = 50000000 * 0.07 = 3500000

50000000 - 3500000 = 46500000

46500000 after 6 hours.

7% of 46500000 = 46500000 * 0.07 = 3255000

46500000 - 3255000 = 43245000

43245000 after 12 hours.

7% of 43245000 = 43245000 * 0.07 = 3027150

43245000 - 3027150 = 40217850

40217850 after 18 hours

7% of 40217850 = 40217850 * 0.07 = 2815249.5

40217850 - 2815249.5 = 37402600.5

37402600.5 after 1 day.

Round up.

There will be 37402601 bacteria after 1 day.
