Answer:
John- 375
Karen- 125
Step-by-step explanation:
Answer 1...
j =3k
2j + k = 875
substituting the first eqn into the 2nd
2(3k) + k = 875
6k+ k =875
7k = 875
k =875/7 =125
thus j = 3(125) =375
 
        
                    
             
        
        
        
16.30 and 16.3 equal. If you ever have a problem like that then you just add on a zero.
Example:
19.4500 = 19.45 Just add two zeros on the end
19.45 + two zeros = 1.4500
