Cutting Edge razor blades come in small, medium and large packages. The small package has 6 blades costing $2 per package, the medium has 12 blades costing $3 per package and the large has 24 blades costing $4 per package. A store sold 12 packages of blades containing a total of 162 razor blades. The revenue made from the sale was $35. How many packages of each type were sold? Solve using G-J Elimination. a. write the system of equations for the information. identify variables b. write the augmented matrix for the information. c. solve using the G-J elimination method and label each answer.
