Jason Rocks produces five different sizes of stones, from small crushed stones (#1 stones) to large (three-inch) rocks (#5 stones). The company mines and sorts 500 tons of stone each day and is a price taker in the local stone market. The table below contains the percentage of each type of stone quarried each day and the market prices.

Selling Prices (per Ton)
Type of stone	% of Daily production	Unwashed	Washed
#1	10%	$210	$219
#2	20	185	192
#3	20	150	170
#4	35	145	155
#5	15	160	165

Daily cost of mining and sorting the stones is $75,000, which includes the salaries and benefits of the employees who quarry and sort the stones, the depreciation on the equipment used in the process, the royalty payments to owners of the quarry for the stone removed, and an allocation of the utilities, insurance, property taxes, and administrative costs of the entire quarry operation. Washing any of the five types of stone costs $8 per ton, and delivering the stone to the local distributor costs $7 per ton. Jason Rocks allocates the mining and sorting costs based on the tons of each type of stone produced.
