Answer:
The answer to your question is 175 gallons
Explanation:
Data
60% antifreeze solution volume = ? = x
25% antifreeze solution volume = 25%
Final concentration 50%
Process
0.6x + 0.25(70) = 0.5(70 + x)
Simplification
0.6x + 17.5 = 35 + 0.5x
0.6x - 0.5x = 35 - 17.5
0.1x = 17.5
x = 17.5/0.1
Result
x = 175 gallons
