A bank teller has a total of 74 bills in five-, ten-, and twenty-dollar denominations. The total value of the money is $920. (a) Find the total number of solutions. (b) Find the solution with the smallest number of five-dollar bills. (c) Find the solution with the largest number of five-dollar bills. (a) Let x be the number of five-dollar bills, y be the number of ten-dollar bills, and z be the number of twenty-dollar bills. Translate the given information into two equations, using x, y, and z as the variables. x+y+z = 74 5x + 10y + 20z = 920 (Do not factor. Use integers or decimals for any numbers in the expressions.) There are a total of solutions.
