A

given that y varies directly as x, then the relationship is

y = kx ← k is the constant of variation

To find k use the given condition x = 3 when y = 24

y = kx ⇒ k = [tex]\frac{y}{x}[/tex] = [tex]\frac{24}{3}[/tex] = 8

y = 8x


as x and y vary directly, then  if x = 3 and y = 24 , the option A IS THE CORRECT, Y = 8X, y = 8*3 =  24
