Depends on what depth you want to spread the gravel at. This answer depends on knowing the cubic capacity of 50 lbs. of gravel.
It depends how deep you want the gravel to cover, if you want it to be 2 inches deep it's going to cost more than 5 inches. Also it depends how big the gravel is cut, I think that the smaller the gravel is the more it costs.
Based on sand and gravel calculator found on L.R. Faulk Construction Co. site, 1 ton of gravel (clean rock) will equal approximately 7.3 sq. ft x 6 inches deep, or 5.2 sq. ft x 3 inches deep. A ton of gravel will cover approximately 15 square yards (135 square feet) at 3 inches deep.

You would need approximately 2.5 cubic yards of gravel to cover a 12' by 15' area at a depth of 2 inches.
2800 feet of gravel
3000 sq ft * 4 inches = 1000 cubic feet.
Gravel averages 100 pounds per cubic foot or 20 cubic feet per ton. That's depth x width x length. So if you want to cover something 6 inches deep, you can cover 40 square feet of surface.
