The ornamental design for a combinedrestaurantcheck and calculator holder, as shown and described.
The combined restaurant check and calculator holder is to be used to discretely present restaurant customers with their bill and to provide the customers with a means to divide the check and calculate a tip. The exterior of the combined restaurant check and calculator holder is to be considered generic but could ultimately be ornamented by the restaurant owner or other advertiser.
The view is a perspective view of the combined restaurant check and calculator holder showing my new design.
