You can put this solution on YOUR website! y varies directly as x. find the constant of variation and the direct-variation equation. y=750 when x=25.
------------
Direct variation implies y = kx
Need to find k which is the constant of variation.
---------------
Since y = 750 when x=25 you get:
750 = k*25
k = 30
