True or false- the use of interchangeable parts, first introduced by eli whitney, increased the price of products. if false explain why.

The answer is false.
Although Eli Whitney did create interchangeable parts, the prices of products did not raise. In fact, they lowered.
Because people were able to make more products now, there was no need to put a high price on them, so the prices were able to lower.
