The supply function for good X is given by QsX. QsX equals to 200 plus 4PX minus 3PY minus 5PW, where PX is the price of X, PY is the price of good Y and PW is the price of input W. If PX is 500, PY is 250, PW is 30, then the supply curve is

Select one:

a.QsX equals to 1300.

b.QsX equals to 4PX minus 550.

c.QsX equals to 150 plus 4PX.

d.QsX equals to 4PX minus 700.
