Given : Dr. Jimenez found that after applying an antibiotic to bacteria,
he observed only 90% of the bacteria left in the culture dish each hour.
The initial bacteria count was 100,
To Find : the bacteria count after 5 hours Round to the nearest whole number.
Solution:
90% of the bacteria left in the culture dish each hour.
Initially = 100
After 1 hrs = (90/100) 100 = (0.9) * 100
After 2 hrs = (90/100) (0.9) * 100 = (0.9)² * 100
After 5 hrs = (0.9)⁵ * 100 = 59.05
≈ 59
Hence There were 59 bacteria after 5 hours.
