Today in grade 11 Functions we all got a question that I am unable to solve. Is it possible that you guys can help me solve it, showing how you got the answer?
In a forest there are twice as many grey moths as there are black ones. The population of the grey moth increases by 3% a month, whereas the black moths increase by 4% a month. How many months would it take for there to be twice as many black moths as grey moths?
I know it involves Log, but for this question I do not know how to use it. I know how to do standard log equations, but it doesn't seem that standard.
