Based on the estimated annual quantities of gases required, the total contract value can be estimated. The estimated annual quantity of liquid nitrogen is 239,868 cubic feet, liquid oxygen is 31,680 cubic feet, and liquid carbon dioxide is 141,813 pounds. Assuming an average price of $0.50 per cubic foot for nitrogen, $1.00 per cubic foot for oxygen, and $0.25 per pound for carbon dioxide, the total annual cost would be approximately $239,868 * $0.50 + $31,680 * $1.00 + $141,813 * $0.25 = $149,934 + $31,680 + $35,453 = $217,067. For a 5-year contract, the total contract value would be approximately $217,067 * 5 = $1,085,335. Therefore, the estimated budget range for this opportunity is between $1,000,000 and $1,200,000.
