The lineal foot cost is easy to calculate - you just take the length in feet and multiply it by the cost per lineal foot. So in your first example, if you bought a six foot length of that board, it would cost you $23.70.

The equation for board feet is (thickness x width x length)/144. All measurements have to be in inches - so your length has to be expressed in inches instead of feet.

Let's assume you buy a six foot board of the same board as the first example. In hardwood, the measurements are the measurements of the rough stock, so if the stock is 4/4 you pay for one inch, even if the finished size is smaller. Same with the width.

Thickness is one inch, width is 8 inches and length is 72 inches for 4 board feet. Since you specified a price of $2.80 per board foot, the price of that board would be $11.20

Some places, like where I buy my hardwood, add 10% (because they can get away with it). Don't ask me how they justify that, but they charge it. So I'd pay $12.32 for that board.

Some wood is sold by the square foot - for example, half inch stock is often priced by the square foot.

Hope that helps. (Hope I didn't make any math errors)
