Question

A culture started with 4000 bacteria after 2 Hours it grew 4400 how many will it grow after 13 Hours

Answer 1

Assuming that the bacteria grows a colony of 200 every hours, then the total of bacteria after the 13th hour would be 200x13 = 2,600, then the total will be added to the original culture which is 4,000 + 2,600 = 6,600 bacteria after 13 hours
