The table shows amounts earned for washing dogs. how much can be earned by washing 8 dogs? dogs, x dollars, y 1 18 2 36 3 54 4 72 a) $144 b) $324 c) $64 d) $126

The correct answer is:  [A]: " $ 144 " .

Explanation:

To solve:

We now, that "y= 8* x"  ;

since:  given the table of values;

when:  x = 1 ;   y = 8* x  =  8 * 1 = 8 ;

           x = 2 ;  y = 8 * x =  8 * 2 = 16 ;          

           x = 3 ;  y = 8 * x =  8 * 3 = 24 ;

           x = 4 ;  y = 8 * x =  8 * 4 = 32.

So:      x = 18  ;  y = 8 * 18  =  144 .

→  that is;  when "x" , the number of dogs, equals:  "18"  ;  

→  "y", the amount in "dollars" ;

          →  equals:  " {18 * 8} " dollars ;  which equals :

          →   " $ 144 " .

          →  which corresponds to:  

  →  Answer choice: [A]: " $ 144 " .

Hope this answer helps!
