Given:
A chemical company makes two brands of antifreeze.
The first brand is 70% pure antifreeze.
The second brand is 95% pure antifreeze.
We need to make 130 gallons of a mixture that contains 85% pure antifreeze.
Let we will use (x) gallons from the first brand
So, we will use (130 - x) from the second brand.
The mixture must contain 85% pure antifreeze.
So, we can write the following equation:
Solve the equation to find (x):
So, the answer will be:
First brand: 52 gallons
Second brand: 78 gallons
