Luxury goods - online puzzles

In economics, a luxury good (or upmarket good) is a good for which demand increases more than proportionally as income rises, and is a contrast to a "necessity good", for which demand increases proportionally less than income. Luxury goods are often synonymous with superior goods and Veblen goods.

The word "luxury" is originated from the Latin word “Luxus,” which means indulgence of the senses, regardless of cost.
