Set up a proportion:

The numerator represents fluid ounces of milk, and the denominator represents milligrams of calcium.
Simplify the first fraction to make multiplication easier:


Cross multiply the fractions:


Divide both sides by 135 to get x by itself:

 2.1 fluid ounces of milk
2.1 fluid ounces of milk provide 72.5 milligrams of calcium.

Answer:
$82.50
Step-by-step explanation:
8.75 * 8 = 70
5 * 2.50 = 12.5 
70 + 12.5 = 82.5
So, one employee would earn a total of $82.50 which also means that each employee earned $82.50
 
        
                    
             
        
        
        
X^2 - 8x  = (x - 4)^2 - 16
we add 16 to  give   x^2 - 8x + 16  which is a perfect square 
x^2 - 8x + 16  = (x - 4)^2
answer is 16
