Ricky wants to have $2,500,000 when he retires in 35 years.

a. How much does he have to save each month if he can earn a 3% annual return compounded monthly?

b. Ricky needs to finance his retirement consumption for 18 years after he retired using the $2,500,000 he have at retirement. Thereafter, his son will support his retirement consumption. How much can he consume each month during the 18 years retirement?

I'm not sure how to hand this..
