not sure what that means? i know y can vary directly with x, but what does it mean "y varies directly with x and y" ? that would mean y = kxy

oh ok if y varies directly with x then \[y = kx\] let x = 16 let y = 48 solve for k

right, that is how you will solve for k. what answer do you get for k ?

3 but in the question it doesnt ask for k and i did write 48=k16 and got it wrong

well we didn't answer the question yet. we can't answer the question without knowing what k is since we solve for k = 3 then we know y = kx y = 3x
