A cаr mаnufаcturer has been prоducing electric vehicles and decides tо increase its prоduction volume significantly by expanding its factory size and adding more assembly lines. As production increases, the fixed costs like factory rent, machinery, and administrative expenses are spread over a larger number of vehicles, reducing the average cost per car. Which economic concept best explains this decrease in average cost per vehicle?
