<u>Answer:</u> The amount of pure antifreeze that must be added is 6.4 gallons
<u>Explanation:</u>
We are given:
Percent of antifreeze given = 10 %
Amount of solution = 8 gallons
Let the amount of pure antifreeze be 'x'
Calculating the amount of pure antifreeze:
Let the amount of pure antifreeze added in the solution be 'y'
Percent of solution to be made = 50 %
So,
Hence, the amount of pure antifreeze that must be added is 6.4 gallons
