A mother wants to save $3000 after every 3 months in a financial institution,

which pays her interest at a rate of 8% per year compounded quarterly

and deposits 28 quarterly payments. After 7 years the mother gives loan

to a company that accumulated amount, which she receives from the bank,

after 7 years at an interest rate of 9% compounded annually. What amount

she will have finally when the company returns the amount to her after 3 years?

How much total interest should she earn in 10 years time?
