They are both correct becuase lets say it was a shirt that was $30 and it was 30% off. For Jasani it would be 30 * 0.7 which equals $9 then you would subtract this 30 - 9 = 21. For Hanna it would be 30 - 0.3(30) which equals $21. So in the end they are both correct!

Answer:
  =4/13
Step-by-step explanation:
There are 13 hearts in a deck 
4 jacks
but 1 is the jack of hearts so we don't double count it
13+4-1 = 16
P( heart or a jack) = jack or heart/ total
                              = 16/52
                              =4/13
 
        
             
        
        
        
To get the inverse, first off do a quick switch on the variables, and then solve for "y".
