Charles Ingalls wants to buy baking soda and a pair of work gloves from "Oleson's Mercantille." Nells Oleson says the baking soda costs US $0.05 and the work gloves cost US $0.27 but Harriet Olson says the baking soda costs US $0.05 and the work gloves cost US $0.47; Charles Ingalls ends up only buying the baking soda.
