You can put this solution on YOUR website! In 2004, the Diabetic Express charged 27.06 for a vial of Humulin insulin and 34.39 for a vial of Velsulin insulin. If a total of 1565.57 was collected for 50 vials of insulin, how many vials of each type were sold?
-------------
Quantity equation: h + v = 50
Value equation:27.06h+34.39v = 1565.57
-------------------------------------------
Solve the system for h and for v
