Please help !!

A small oil company wants to replace its Micro Motion Coriolis flowmeters with Emerson F-Series flowmeters in a site construction. The replacement process will cost the company $55,000 four years from now. How much money must the company set aside each year beginning one year from now in order to have the total amount in three years? Assume the company will invest its funds at 15% per year. Bodine Electric makes gear motors with a three-stage, selectively hardened gearing cluster that is permanently lubricated. If the company borrows $25 million for a new warehouse/distribution facility, determine the annual payments to repay the loan in five equal annual payments at an interest rate of 8% per year? One of life's great lessons is to start early and save all the money you can! If you save $1 today and $1 each and every day thereafter until you are 60 years old (say $365 per year for 35 years), how much money will you accumulate if the annual interest rate is 10%
