Hey, if anyone is good at Algebra 2, please help with this problem! "The AP chemistry class is mixing 100 pints of liquid together for an experiment. Liquid A contains 10% acid, liquid B contains 40% acid, and liquid C contains 60% acid. If there are twice as many pints of liquid A than liquid B, and the total mixture contains 45% acid, find the number of pints needed for each liquid."
