Question 1096163: the weight W that can be lifted by an automobile jack varies directly with the force F exerted downward on the jack handle. Suppose that a force of nine pounds will lift nine hundred and fifty-four pounds. use direct variation to write a complete model that expresses W as a Function of F
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
w = k * f

w is the weight
k is the constant of variation
f is the force.

then the force is 9 pounds, the weight lifted is 954 pounds.

formula becomes 954 = k * 9

solve for k to get k = 954 / 9 = 106

formula becomes w = 106 * f

that's what you are looking for i believe.
