A waiter made $229 during his shift. At the end of the night, he had 66 bills consisting of ones, fives, tens, and twenties. The number of fives is four times the number of tens, and the number of ones is one less than twice the number of fives. Let x=#ones, y=#fives, z=#tens, w=#twenties. a. Set up the system of equations representing this scenario b. Write your system of equations into an augmented matrix (you do not need to solve the system)
