Answer:
[tex]\dfrac{2}{3}[/tex]
Explanation:
From the given information:
Since the box ranges from 450 to 600 on the number line; then the capacity of the dunk tanks = 600 - 450 = 150 gallons
Suppose the dunk tank requires 500 gallons of water; then 500 to 600 on the number line = 600 - 500 = 100 gallons.
Thus, the fraction of the dunk tanks that requires at least 500 gallons of water is: =[tex]\dfrac{100}{150}[/tex]
In the simplest form; we have:
[tex]=\dfrac{2}{3}[/tex]
