Maria is thinking about buying a car. She figures her monthly payments will be $90 for insurance, $30 for gas and $20 for general maintenance. The car she would like to buy may last for 4, 5 or 6 years before a major repair with probabilities of 0.4, 0.4 and 0.2 respectively. Calculate the present worth of the expected expenses over the expected life of the car before a major repair if Maria's MARR is 16%, compounded monthly.
