Question

a chemical company mixes pure water with their premium antifreeze solution to create an inexpensive anti-freeze mixture. the premium antifreeze solution contains 85% pure antifreeze. the company wants to obtain 170 gallons of a mixture that contains 80% pure antifreeze. how many gallons of water and how many gallons of the premium antifreeze solution must be mixed? water: __ Gallonspremium anti-freeze: __Gallons

Answer 1

Given data:

The expression for the gallon of premium antifreeze is,

$\begin{gathered} 0.85x=170\times0.80 \\ x=160 \end{gathered}$

The volume of the water is,

$\begin{gathered} w=170-x \\ =170-160 \\ =10 \end{gathered}$

Thus, the volume of water is 10 gallons, and volume o antifreeze is 160 gallons.
