Nikole invested $2,160 into an account that earns 3.26% interest compounded semi-annually. How long will it take (in years and days) to accumulate to $8,270. (1 year = 365 days)

Days are rounded up to the next days (e.g. 17.2 days becomes 18 days). Do not enter 365 days (e.g. 7 years 365 days, must be entered as 8 years 0 days). If years is a whole number, you must enter a zero for days for the answer to be marked as correct. All answer boxes must have an entry!
