Question

The market supply curve is the horizontal sum of all the individual supply curves.

Answer 1

The statement is true. In every market structure, the demand provides the number of goods bought by both buyers and sellers. The summation of each demand at every given price. It is because the summation of the commodities is over quantities for prices. Similarly, it goes in hand with the law of supply, whereby it indicates the quantity supplied at every given price by the producers.
