Q7. Your cousin has just started saving for retirement. She is 25 and asked you to help her determine the amount she will have accumulated for retirement in 40 years. For the first 10 years she plans to contribute $3000 a year. Then in years 11-20 she plans to increase her contribution to $5000 a year. In years 21-30 she plans to contribute $10,000 a year and in the last 10 years she plans to contribute $15000 a year. Assume she gets a steady rate of 6%. How much will she have accumulated. Then compute the annual payment she will receive over the next 40 years if the wealth is converted into an annuity payment at 8%.
