A chemical manufacturer wants to lease a fleet of 28 railroad tank cars with a combined carrying capacity of 456,000 gallons. Tank cars with three different carrying capacities are available: 6,000 gallons, 12,000 gallons, and 24,000 gallons. How many of each type of tank car should be leased? Let x1 be the number of cars with a 6,000 gallon capacity, x2 be the number of cars with a 12,000 gallon capacity, and x3 be the number of cars with a 24,000 gallon capacity. Select the correct choice below and fill in the answer boxes within your choice. A. The unique solution is x1=nothing, x2=nothing, and x3=nothing. (Simplify your answers.) B. There are multiple possible combinations of how the tank cars should be leased. The combinations are obtained from the equations x1=nothingt+(nothing), x2=nothingt+(nothing), and x3=t for nothing≤t≤nothing. (Simplify your answers. Type integers or simplified fractions.) C. There is no solution.
