Answer:
4 gallons of water.
Step-by-step explanation:
1. There is 1 gallon of 10% solution
2. There is 2% saline in water
3. The equation is 10% of 1 gallon = 2% of solution of x gallons of water + saline
0.1 = 0.02(x + 1)
Subtracting 0.02 from both sides, we get
0.1 -0.02= 0.02x +0.02 -0.02
0.08 = 0.02x
Dividing both sides by 0.02, we get
0.08/0.02 = 0.02x/0.02
x = 4.
4. The answer is 4 gallons of water.
