A chemist creates 220 milliliters of a 32.5% alcohol solution by combining a 15% alcohol solution with a 50% alcohol solution. If x represents the amount of the 15% alcohol solution used and y represents the amount of the 50% alcohol solution used, which of the following could be used to model the given information?
The model that could be used to represent the given information is the equation:
0.15x + 0.50y = 0.325(220)
