lauren plans to deposit $8000 into a bank account at the beginning of next month and $150/month into the same account at the end of that month and at the end of each subsequent month for the next 4 years. if her bank pays interest at a rate of 5%/year compounded monthly, how much will lauren have in her account at the end of 4 years? (assume she makes no withdrawals during the 4-year period. round your answer to the nearest cent.)
