How much was john rolfe's tobacco crop worth?

The correct answeer to this opne question is the following.

In those early years of growing tobacco in Jamestown, Virginia, there was no money. The equivalent were "notes" that could be exchanged for goods. Virgina average an annually production of tobacco of 70,000 barrels or hogsheads, as they were called in those years. Every barrel weighted about 1,000 pounds. That was the standard measure. So in a year, Virginia farmers grew 70,000,000 pounds of tobacco.

Regarding the price of this cash crop, a pound of tobacco had a price of 2.5 cents per pound. So the profit in dollars in a year was $1,750,000.

That is why John Rolfe's tobacco became the king of cash crops in colonial Virginia. It was very well accepted in Europe. So most of ot was exported.  

in contrast, the biological controls are self-sustaining, inexpensive and very effective once established. biological control could be used on thousands of golf course acres, improving their biodiversity and quality as wildlife habitat. in the process, the golf industry will be shown to be leaders in an environmental stewardship program of benefit not only to the lands they manage but also to the watersheds in which they exist.

b) they want the land taken away from the wealthy landowners and given to peasants.
