Question

a culture started with 4,000 bactira . after 4 hours , it grew to 5,200 bactira . predict how many bactira will be present after 11 hours . round your answer to the nearest whole number p=AE^kt

Answer 1

Answer: 7300

Step-by-step explanation: 5200 - 4000 = 1200. 1200 divided by four hours is 300. So 300 bacteria grow per hour. Then you multiply 300 by 11 hours and get 3300 bacteria plus the starting 4000 and your final number is 7300
