Substituting the numbers into the simple interest formula, we get I=. p r t 1,680=(3000)(r)(8). Multiplying 1,680= 24,000r Divide both sides by 24,000  0.07= r So, the percentage is (0.07)(100)= 7%... Well, Anita, I am glad to help out...

X=2   its x=2 because you have to divide -20x by -40 so the two negatives cancel out each other and then you get 2. 
        
                    
             
        
        
        
Answer: 
$5.08 
Step-by-step explanation: 
Step one:
given data
We are told that a credit card company applies a 6% fee on all transactions under $10
since the cost of coffee bellow $10 that is $4.80, the 6% fee is applicable
so
=6% of 4.80
=6/100*4.80
=0.06*4.8
=$0.288
Step two:
the total fee will be  
=0.288+4.80
= $5.08
