Judith has just become eligible to participate in her company's retirement plan. Her company matches her contributions dollar for dollar. The plan averages an annual return of 13 percent interest compounded annually. Judith is 40 and plans to work until age 65. If she contributes $220 per month and assuming that the account will continue to return 13 percent per year compounded annually, how much will she have in her retirement plan at retirement? Can somebody please show me the work to solving this question?
