Question

Dr. Jimenez found that after applying an antibiotic to bacteria, he observed only 90% of the bacteria left in the culture dish each hour. If the initial bacteria count was 100, what was the bacteria count after 5 hours? Round to the nearest whole number. There were bacteria after 5 hours.

Answer 1

59 on edge

Explanation:

Answer 2

Count = 100(0.90)^t where t = number of hours

after 5 hours the count will be 100*(0.90)^5 = 59 to nearest whole number
