A person invests part of his $10 000 savings in a bank at 6%, and part in a certificate of deposit at 8%, both simple interest. He gets a total of $750 per year in interest from the two investments. How much is invested at each rate?

How much steel containing 5.25% nickel must be combined with another steel containing 2.84% nickel to make 3.25 tonnes of steel containing 4.15% nickel?

Thanks
