can I get a step-by-step answer? thanks!

John has $50,000 in an investment account. His goal is to have the account grow to $100,000 in 10 years without having to make any additional contributions to the account. What annual rate of interest would he need to earn on the account in order to meet his goal? Hint. To calculate return on investment use the interest (1/Y) key on the financial calculator. 8.07% 7.17% o 10.23% 9.65%
