How many gallons of a 60 percent antifreeze solution must be mixed with 70 gallons of 10 percent antifreeze to get a mixture that is 50 percent antifreeze?
Suppose G gallons of 60% antifreeze are required. G gallons of 60% contain 0.6G gallons of the active ingredient. 70 gallons of 10% contain 7 gallons of the active ingredient. So, in the mixture, there are G + 70 gallons containing 0.6G + 7 gallons of the active ingredient. This is to represent 50%. So 0.6G + 7 = 0.5*(G + 70) = 0.5G + 35 0.1 G = 35 - 7 = 28 G = 280 gallons.

-2
How many gallons of a 12 percent indicator solution must be mixed with a 20 percent indicator solution to get 10 gallons of a 14 percent solution?
Let x represent the amount of 12% solution and (10-x) represent the amount of 20% solution. The equation to solve is: 0.12x + 0.20(10-x) = 0.14(10). Solving for x gives x = 4, so you need 4 gallons of the 12% solution and 6 gallons of the 20% solution to make 10 gallons of the 14% solution.
Is -.7 percent less than -12 percent?
