to start: this question has been posted and answered at https://chegg.com/homework-help/questions-and-answers/please-show-work-5-susie-lisa-45-years-old-investing-different-amounts-money-different-len-q125036702 -

however, maybe it can be reexplained as they say susie's initial FV is over $30,000, when $20 a month for 180 months is only 3600. maybe i am overthinking but a second opinion would be very helpful

please show work and calculations.

5. Susie and Lisa are both 45 years old but have been investing different

amounts of money for different lengths of time.

a) Determine the total future value of each portfolio.

Susie's portfolio: Susie saved $20 each month for 15 years at an

average interest rate of 3.2% compounded monthly until she was 25.

Then she reinvested the entire amount at 3.8 % compounded monthly for 10 years.

Lisa's portfolio: Lisa has been depositing $25 each month for the past

12 years into a savings account that earns an average annual interest

rate of 3.6% compounded monthly.

b) Determine the Rate of Return (ROR) for each portfolio.
