Johanna has saved $18000 over the last 10 years. She decides to invest some of it at 4.75% annual interest and the rest at 3.25% annual interest. After one year, her total interest from both accounts is $750. How much did she invest in each account? (Clearly label which amount is for which account in your answer. A. Define variables to represent the unknowns and setup the necessary equations to answer the question. B. Algebraically solve the equation you created and express your final answer using a complete sentence and appropriate units. (You will not receive full credit if a trial and error method is used in place of an algebraic method.)
