So he has $40 in the bank. So first he buys gas for $40 , then writes a check for 64.75. So it would be 40-40-64.75= -64.75
        
             
        
        
        
 Just do 27/39 to find how much 27 is of 39, and then subtract that from 100 to get the percentage of discount.
27/39 is about 0.69
So the rate of discount is about 0.31 
Hope this helps!
