Hi! This is a finance-based problem, which might be my difficulty. I have the answers from the book. Here is the prompt: "Suppose that a sum $$S_0$$ is invested at an annual rate of return $$r$$ and compounded continuously. (a) Find the time $$T$$ required for the original sum to double in value as a function of $$r$$. (b) Determine $$T$$ if $$r=7\%$$. (c) Find the return rate that must be achieved if the initial investment is to double in $$8$$ years.
