Answer :
Jamestown succeeded economically by planting and selling tobaccos.
Initially the people that came to start a colony in Jamestown had to go through
a lot of hardship as the water was not good and there were a lot of mosquitoes.
The men fell sick and did not find enough food to eat. Later they started
planting tobacco plants and became rich by exporting them to England. By the
year 1675 Jamestown exported almost ten million pounds of tobacco each year.
Tobacco was the cash crop of Jamestown. The colonists had trouble with planting things because they did not know much about agriculture, but through the help of Indians, they were able to become successful by growing and selling tobacco.
