Step 1 :Given that the amount of money accumulated after n years, including interest (A) is $98,700, the annual interest rate (r) is 2.14% or 0.0214 in decimal, the number of times that interest is compounded per year (n) is 365, and the time the money is invested for in years (t) is 13.
Step 2 :We need to find the principal amount (P). So, we rearrange the formula for compound interest to solve for P: \(P = \frac{A}{(1 + \frac{r}{n})^{nt}}\)
Step 3 :Substitute the given values into the formula: \(P = \frac{$98,700}{(1 + \frac{0.0214}{365})^{365*13}}\)
Step 4 :Simplify the expression inside the parentheses: \(P = \frac{$98,700}{(1 + 0.00005863013698630137)^{4745}}\)
Step 5 :Calculate the value of the expression inside the parentheses: \(P = \frac{$98,700}{1.308677927}\)
Step 6 :Finally, calculate the value of P: \(P = $75,388.68\)
Step 7 :So, Hans would need to invest approximately \(\boxed{$75,389}\) to have $98,700 after 13 years, assuming an interest rate of 2.14% compounded daily.
