A experiment calls for 60 gallons of a 60% saline solution. You only have a 70% saline solution and a 40% saline solution. Let x represent the amount of 70% saline solution and y represent the amount of 40% saline solution, what is the equation that describes the total amount of pure saline in the solution? O x(0.7) – y(0.4) = 60(0.6) O x(0.4) + y(0.7) = 60(0.6) O x(0.4) – y(0.7) = 60(0.6) O x(0.4) + y(0.7) = 60(1.1) O x(0.7) + y(0.4) = 60(0.6)
