Hello people, i got this log question and it took me ages and i still can not figure it out, can anyone explain this to me?
Q: The population of Cda is 30 m and is growing at an annual rate of 1.4%
The population of Ger is 80 m and is decreasing at an annual rate of 1.7%
In how how many years will the population of Cda be equal to the population of Ger?
(use log to solve the resulting equation and to 2 decimal places)
The answer is 31.59 yrs but i have no idea how to do it, any ideas?
