Exponential Growth If you are asked to find the t in the exponential growth equation y=C(1+r)^t how would you find it. Example 1.2487 ≤ 1.021^t Would you have to guess and check or is there another way to solve

No idea XD

1.2487 ≤ 1.021^t take the log of both sides

log 1.2487 ≤ log 1.021^t an we can write

log 1.2487 ≤ t * log 1.021 divide by log 1.021

log 1.2487 / log 1.021 ≤ t

10.687 ≤ t

Thank you
