Answer:
B, $1.32
Step-by-step explanation:
100 grams is 0.1 kilograms, and 25 grams is 0.025 kilograms. The difference is 0.075 kilograms. At $17.60 per kilogram, 0.075 kilograms would cost  $1.32 or answer choice B.
 
        
             
        
        
        
The solution is -5/4= -1 1/4
        
                    
             
        
        
        
Percent means per one hundred so we can say that:
p/100≈(28)/(28+81+45+63+35)  guessing with my old eyes :)
p/100≈28/252
p≈2800/252
p≈11.11%
So rounded to the nearest 5% you'd have:
p≈10%
