  1. Calculate Weight Difference: Calculate the weight of the old bookshelf by subtracting the weight of the cart from the total weight of the bookshelf and the cart. Use the formula Weight of the old bookshelf=Total weight of the bookshelf and the cartWeight of the cart.\text{Weight of the old bookshelf} = \text{Total weight of the bookshelf and the cart} - \text{Weight of the cart}.
