Erbitux is a colorectal cancer treatment drug that is manufactured by ImClone Systems, Inc. If the treatment takes place over a 1 year period at a cost of $10,000 per month and the patient lives 5 years longer than he/she would have lived without the treatment, how much would that person have to earn each month beginning 1 month after treatment ends in order to earn an amount equivalent to the total treatment cost at an interest rate of 12% per year compounded monthly?
