Amixture contains forty ounces of glycol and water and is ten percent glycol. if the mixture is to be strengthened to twenty-five percent, how much glycol is to be added?

40oz glycol and water

10% is glycol

4oz is glycol

36oz is water

if glycol is to be added to make glycol 25% of all then

note: water does not change

100-25=75

water does not change so

36oz=75%

12=25%

there should be 12 oz of glycol total

4 now

12-4=8

8 oz should be added

sorry, I just wrote what I was thinking

answer is 8oz
