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!

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
