A food server examines the amount of money earned in tips after working an 8-hour shift. The server has a total of $191 in denominations of $1, $5, $10, and $20 bills. The total number of paper bills is 53. The number of $5 bills is 4 times the number of $10 bills, and the number of $1 bills is 1 less than twice the number of $5 bills. Write a system of linear equations to represent the situation. (Assume x = number of $1 bills, y = number of $5 bills, z = number of $10 bills, and w = number of $20 bills.) x + y + z+ W = 191 z + W = 53 y - x - -1 Use matrices to find the number of each denomination. $1 bill(s) $5 bill(s) $10 bill(s) $20 bill(s) x3= y = z =
