We present results for the QCD equation of state, quark densities, and susceptibilities at nonzero chemical potential, using 2+1 flavor asqtad ensembles with N{sub t}=4. The ensembles lie on a trajectory of constant physics for which m{sub ud}{approx_equal}0.1m{sub s}. The calculation is performed using the Taylor expansion method with terms up to sixth order in {mu}/T.
