Step-by-step 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:
