Find the missing values assuming continuously compounded interest. Given the Initial Investment $800 and after 10 years $2005, find annual % rate and time to double in yrs.

Question

Continue to struggle to find and figure out the proper way, this is the only math assignment that has been giving me a hard time overall and I can't wrap my head around it.

Answer 1

2005 = 800e^10r

2.50625 = e^10r

ln 2.50625 = 10r

0.9188 ≈ 10r

0.0918 ≈ r

2 = e^0.0918t

ln 2 = 0.0918t

Can you solve for t and answer?
