The estimated budget for this contract can be determined by considering the anticipated annual consumption of each product and the cost per gallon. For Bid #1 (Off-Road Diesel Fuel), the anticipated annual consumption is 25,000 gallons. For Bid #2 (Regular Unleaded Gasoline), the anticipated annual consumption is 2,000 gallons. For Bid #3 (Bulk Motor Oil), the anticipated annual consumption is not specified, but for Bid #4 (Diesel Exhaust Fluid), it is 300 gallons (or 600 gallons in 2.5-gallon containers). Assuming an average cost per gallon of $2.50 for diesel fuel, $2.75 for gasoline, $5.00 for motor oil, and $3.00 for diesel exhaust fluid, the total estimated budget would be: 25,000 gallons * $2.50/gallon = $62,500 (diesel fuel) 2,000 gallons * $2.75/gallon = $5,500 (gasoline) 300 gallons * $3.00/gallon = $900 (diesel exhaust fluid) The total estimated budget for the contract would be around $68,900, not including the cost of motor oil, which is not specified. However, considering the total estimated budget for all products, including motor oil, the estimated budget range could be between $100,000 and $200,000.
