1. A foldable cart comprising: a base frame;a plurality of wheels coupled to the base frame;a lower vertical support frame having two ends, a first end being pivotally connected to the base frame to fold against the base frame in a closed position and to extend to a vertical position against the base frame in an open position to form a back wall of the cart;an upper vertical support frame having two ends, a first end being pivotally connected to the second end of the lower vertical support frame that is opposite the base frame first end so that the upper vertical support frame folds against the lower vertical support frame in the closed position, the second end having a top rail; anda hanger rod having two ends, a first end being pivotally connected to the top rail at the second end of the upper vertical support frame opposite the first end of the upper vertical support frame so that the hanger rod rotates about the top rail to fold against the upper vertical support frame in a folded position and to extend outward horizontally over the base frame from the pivotal connection of the top rail of the upper vertical support frame in an extended position;wherein the upper vertical support frame is narrower at the second end than at the first end and the hanger rod extends from the center of the top rail so that when the hanger rod is folded into the upper vertical support frame and the upper vertical support frame is folded into the lower vertical support frame with the lower vertical support frame in the open position, then the upper vertical support frame and the hanger rod form additional surface areas on the back wall of the cart. 2. The foldable cart of claim 1, wherein the hanger rod has a folded position parallel with and encompassed by vertical side rails of the upper vertical support frame, the folded position being 90 degrees from the extended position. 3. The foldable cart of claim 1, wherein the hanger rod is formed from a single rod connected at the pivotal connection to the upper vertical support frame, the single rod rotatable to extend over the base frame in the extended position to carry items fully supported by the rod. 4. The foldable cart of claim 1, wherein the lower vertical support frame second end has a top rail which extends to a position away from the base frame, wherein the upper vertical support frame is coupled to the top rail lower vertical support frame, the top rail having hand grips for pushing the cart. 5. The foldable cart of claim 1, wherein the wheels are pivotally mounted to fold against the base frame. 6. The foldable cart of claim 1, wherein in a folded position the base frame forms a first layer and the hanger rod, upper vertical support frame, and lower vertical support frame combined form a second layer above and parallel to the first layer. 7. The foldable cart of claim 1, further comprising a handle pivotally connected to the base frame opposite the lower vertical support frame to fold against the base frame. 8. The foldable cart of claim 7, wherein the handle has a folded position against the folded upper and lower vertical support frames. 9. The foldable cart of claim 1, wherein the pivotal connection of the upper vertical support frame to the lower vertical support frame comprises two concentric tubes, one tube within the other tube, one tube being a part of the upper vertical support frame and the other tube being a part of the lower vertical support frame. 10. The foldable cart of claim 9, wherein the concentric tubes form a horizontal bar having a hand grip for pushing the cart. 11. The foldable cart of claim 9, further comprising pins extending through holes in the concentric tubes to lock the upper vertical support frame in an unfolded position with respect to the lower vertical support frame. 12. The foldable cart of claim 11, wherein the pins are coupled to a spring to push the pins toward the holes. 13. The foldable cart of claim 9, further comprising a slide plate to engage a groove in at least one of the concentric tubes to hold the tube in an unfolded position. 14. The foldable cart of claim 13, wherein the slide plate engages a notch in the at least one concentric tube and includes a finger notch for engaging and disengaging the slide plate in the groove. 15. The foldable cart of claim 5, further comprising an actuator between the wheels and the lower vertical support frame to fold against the base frame when the lower vertical support frame is folded against the base frame. 16. The foldable cart of claim 5, wherein the actuator comprises angled surfaces connected to the wheels and configured to rotate with movement of the lower vertical support frame.
