I need explanation and steps for this!

If I understood the question correctly, then the equation has the general form of y=kxy=k\sqrt{x}.
When x=5 and y = 35, you have 35=k535=k\sqrt{5} . Can you solve for k? After that, you can plug in k and x=22 in the general form and solve for y.

I realize that the answer is listed in terms of x\sqrt{x}, but if y varies directly with x then y = kx.

So, why is x\sqrt{x} there, and what equation is it saying to solve?

I think the question is defective, or at least misleading.
 
To be crystal clear, there is a typo in the problem and where it says sqrt(x) it should just be x.
