A leak in a pool causes the height of the water to decrease by 0.25 foot over 2 hours. After the leak is fixed, the height of the water
is 4.75 feet. The equation 4.75 = x+(-0.25) can be used to find x, the original height of the water in a pool.
What was the original height of the water in the pool in feet?
4.5
