Question

A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 80% pure antifreeze. The company wants to obtain 160 gallons of a mixture that contains 20% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed? Note that the ALEKS graphing calculator can be used to make computations easier. Water: gallons ? Premium antifreeze: gallons

Answer 1

11) The company wants to obtain 160 gallons solution - The premium antifreeze solution Contains 80% pure antifreeze. of a mixture that contains 20% pure antifreeze. Mixture = 160 gallons pure Antifreeze in mixture = 160x20 loo 32 gallons bet premium antifreeze solution in mixture x gallons 2x 80 32 tot 32:X100 80. x = 40 gallons Mixture = Premium antifreeze solution + pure water 160 at pure water 160 -ų0 120 galcons Water : 120 gallons Premium antifreeze : 40 40 gallons pure water
