Alright, so this is simple. 
P= 50,000 or 50 thousands
G= 13 Tons
The variable f isn't known. 
So your equation would be 13 = 50 (f), if you were to put your known variables in the equation.
If you were to find variable f, you would divide 13 tons by 50,000 to get 0.00026 or in scientific notation: 2.6 x 10 (exponent(s):-4) 
 
        
             
        
        
        
9.5 because 9.5-7 is 2.5. 2.5 times 4/5 is 10/5 which is equivalent to 2. 4/5(2.5-7)=2
        
             
        
        
        
Observations can you make from a comparison of the number of water supply stoppages reported by owner-occupied units versus renter-occupied units 1.
Total no. of times owner-occupied units had a water supply stoppage lasting 6 or more hours 
547000 + 5012000 + 6110000 + 2544000 + 557000 = 14770000
x = no. of times owner-occupied units had a water supply stoppage.
<h3>What is the probability at x =0?</h3>
P(x=0) = 547000/14770000
P(x=0) = 0.0370
Similarly, we have at x=1
P(x=1) = 5012000/14770000
P(x=1) = 0.3393
P(x=2) = 6110000/14770000
P(x=2) = 0.4137
P(x=3) = 2544000/14770000
P(x=3) = 0.1722
P(x=4) = 557000/14770000
P(x=4) = 0.0378
x           f(x)
0             0.0370
1              0.3393
2         0.4137
3              0.1722
4         0.0378
Total      1

Lets say x is quantity
65%x+25%(600-x)=45%of 600
.65x+.25(600-x)=.45*600
.65x+150-0.25x=270
0.4x=120
x=300ml
