Answer:
The difference is 30%
Step-by-step explanation:
To find the percent decrease, start by finding the difference in costs. 
42.54 - 29.78 = 12.76
Now divide that amount by the original cost. 
12.76/42.54 = 30%
 
        
             
        
        
        
3/7= 0.428571
3/6= 0.5
3/5= 0.6
So 3/5 is the greatest of all of them.
