Question

Suppose that a local trout population exhibits exponential growth by doubling every 4 years. Considering that the initial population were 375 trout. How many trout will there be after 1 year?

Answer 1

Hmm, Well it takes 4 years for it to equal the original number times 2. So 2 years would equal half of the population was added. 1 year would equal 1/4 of the original population has been added. If you multiply 375 by 1.25 then you get 468.75. You can't have part of a trout so you would have 468.
