$5,000 is invested in two different accounts yielding 3% and 3.5% interest. The amount invested in the account that yields 3% interest is $550 more than the other account. Establish the equations necessary to find the amount of money invested in each of the accounts. Let x and y represent the two amounts invested. Complete your work in the space provided. Include the entire process for establishing a set of equations, the solution, and an explanation of what the solution means in terms of the variables. Follow the process for establishing a set of equations: Choose a variable to represent one of the unknowns. Express the remaining unknowns in terms of the variable you chose in step 1. Look for a relationship between the unknowns given in the problem. Write an equation. (Look for the other relationship given in the problem.)
