I am trying to fill in the blanks here and come up with a graph and trendline
forecasting sales in $.10 increments when I have history of sales at .99,
1.49, 1.99, and 2.49. Obviously as the price goes up, unit sales come down.
So how can I forecast what might be sold at all these price points.

Thanks in advance.
