The equilibrium is the price that comes out from adding all the direct related costs in producing the good or service. To this total you have to add the indirect costs, for example, taxes, salaries, etc. Add up both results and you will have the price.
The equilibrium price is the price that covers all your expenses, both direct and indirect. With this price you do not lose nor earn any money.
The telegraph
Samuel Morse sent the first telegraph message from Washington DC to Baltimore in 1844. The message he sent said, "What hath God wrought?"
Within a decade, thousands of miles of telegraph cable lines were in use all over the United States, and then by the 1860s a transatlantic cable connected the USA to Europe for communication.
Starting in the mid 1800s, hoards of people traveled to the west out of desire to find land, and there was offered land under the Homestead Act. This was a series of acts that was passed in the year 1862 and it offered 160 acres of land to the settlers. I hope the answer helps you.
