Math word problem!
I can't figure out how to solve this problem, someone please help!
Thanks Lori-Jean Jen's car had a large radiator that contained an unknown amount of pure water. She added two quarts of antifreeze to the radiator. After testing, she decided that the percentage of antifreeze in the radiator was not large enough. Not knowing how to solve a mixture problem, Jen decided to add one quart of water and another quart of antifreeze to the radiator to see what she would get. After testing she found that the last addition increased to percentage of antifreeze by three percentage points. How much water did the radiator contain originally? |
