Commodities generally sell at their value, which is the sum of the value of all the input commodities (which I’m pretty sure Marx calls raw materials) and the final input of labor power needed to make those raw materials into a new product. Demand adjusts according to the price (people may want something, but not at the price offered). What’s important is that the seller makes a profit selling the commodity at its value, not by doing a markup of any sort. This is because the wage paid to the worker is less than the value they create. The worker is not compensated for all of the value they create. This is where profit comes from.
Read Value, Price, and Profit for a synopsis of some ideas provided in Capital.
