The amount of water that is needed to fill the pool is equal to the volume of the pool.
The pool is rectangular, with uniform depth so the volume of pool will be the product of its length , width and depth.
Thus,
Volume = 25 x 18 x 6 = 2700 ft³ 
This means, 2700 ft³ water is needed to fill the pool.
        
                    
             
        
        
        
I got x=0 because I simplified both sides of the equation and then isolated the equation
        
             
        
        
        
Answer:
store a
Step-by-step explanation:
Store A: 25% off on $80 is $20, so the sneakers would be $60. Take 10% of $60 to get $6 off. The sneakers at Store A would cost $60 - $6 = $54. Store B: 20% off on $80 is $16, so the sneakers would be $64. Take 15% of $64 to get $9.60 off. The sneakers at Store B would cost $64 - $9.60 = $54.40.
 
        
             
        
        
        
If the rounding is to the nearest ten, then the greatest one 
is  67,404  and the smallest one is  67,395 .
If the rounding is to the nearest hundred, then the greatest one 
is  67,449  and the smallest one is  67,950 .
        
             
        
        
        
I want to say 66 also because they are the same but I may be wrong
