Final answer:
To derive a market supply curve, you add up the quantities supplied by each producer at each price level. This creates the total market quantity supplied at various prices, which can be graphed as the market supply curve.
Step-by-step explanation:
To derive a market supply curve from individual supply curves, the correct approach is to add up quantities supplied by all individual producers for each price. This is because a market supply curve is a horizontal summation of all the individual supply curves. Essentially, for each possible price level, you combine the quantities provided by all firms at that price. This aggregation process will give you the total quantity that would be supplied in the market at each price point.
The other options listed, such as calculating the average quantity supplied or using the largest quantity supplied, would not result in an accurate market supply curve. Adding up prices paid does not create a supply curve either, as the supply curve is about quantities that producers are willing to supply at different prices, not prices themselves. To visualize this process, one can draw a graph with the aggregate quantities at each price level which will illustrate the market supply curve.
