1.) FINDING THE REQUIRED INTEREST RATEYour parents will retire in 20 years. They currently have $260,000 saved, and they think they will need $900,000 at retirement. What annual interest rate must they earn to reach their goal, assuming they don't save any additional funds? Round to TWO decimal places.

2.) TIME TO REACH A FINANCIAL GOAL You have $51,238.94 in a brokerage account, and you plan to deposit an additional $4,000 at the end of every future year until your account totals $250,000. You expect to earn 13% annually on the account. How many years will it take to reach your goal? Round UP to the nearest year. (Example 5.01 years = 6 years) Your answer should include numerical value only.
