Final answer:
The introduction of the assembly line by Henry Ford resulted in a significant reduction in the price of motor cars, specifically the Model T.
Step-by-step explanation:
The introduction of the assembly line by Henry Ford resulted in a significant reduction in the price of motor cars. The production efficiency brought about by the assembly line allowed Ford to take advantage of economies of scale, which led to a decrease in production costs. As a result, the price of the Model T dropped from over $800 to under $300 over a period of time.
This reduction in price made the Model T more affordable for a larger share of the population, and it contributed to the increased sales and popularity of the Model T.
By using mass production and the assembly line, Ford was able to produce a large number of cars in a shorter amount of time, which allowed him to offer the Model T at a lower price point.
