Daisy Abarca , A good replacement tire and rim can be purchased from a good local auto recycling/wrecking yard $25-$75.00 depending on rim type(aluminum). But that is not the big concern here, if you hit something hard enough to bend the rim there may be hidden damage eg. damaged hub/bearing,rear axle,strut,sway bar,links,etc.. All this should be checked out for (safety) and driveability. The labor rates are usually a lot less at a good local body shop then Dealer or mechanics shop and deal with this type of occurrence all the time, if able have a technician take a look, diagnose and estimate repair. As stated before all parts can be good salvaged parts, at a fraction of cost of new. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
