y = ----------------   = (3/5)x - 4  (answer)
           -5
        
             
        
        
        
Think I know why don't you do the math cadence man all you said is "oh how many more pennies are produced in half a year really not even giving us any numbers it doesn't matter what device were on we can always look up the answer online your lucky
