Question 39687: So Confused!! I'm much older than the average student you normally assist; however, I have recently received notice via contract form from a oil company who are interested in setting and drilling on some property which has been in my family for generations. They are offering me 3/16 of the royalties from oil or gas saved at the well and they have also offered the same amount to seven of my family members, each of us have received contracts indicating the offer of 3/16 and I'm not sure how much this actually is on a per dollar scale?, I believe 3/16 of a dollar or 100 is approximately 19 cents on the dollar which would make it impossible to pay eight persons 19 cents on the dollar and the oil company make money. It may be a percentage; however, a percentage is not indicated on the contract just 3/16 and a lawyer indicated the 3/16 is a fair offer and will be paid to me monthly. Sorry for the long explanation.. can you please determine what they mean by 3/16 and or how much they are actually offering each of us on a per 1.00 scale.
Thank You, Lucille
