A chemical manufacturer wants to lease a fleet of 25 railroad tank cars with a combined carrying capacity of 260,000 gallons. Tank cars with three different carrying capacities are available: 5,000 gallons, 10,000 gallons, and 20,000 gallons. Letting t=number of 20,000 railroad tank cars in the fleet, 2t -2 5,000-gallon railroad tank cars, and - 3t + 27 10,000 gallon railroad tank cars will be in the fleet for a certain range of t. The cost of leasing a 5,000-gallon tank car is $550 per month, a 10,000-gallon tank car is $650 per month, and a 20,000-gallon tank car is $950 per month. Which of the solutions to the number of each type of tank car in the fleet would minimize the monthly leasing cost? 5,000-gallon tank cars, 10,000-gallon tank cars, and 20,000-gallon tank cars. (Simplify your answers. Type whole numbers.)
