Question
A chemical manufacturer wants to lease a fleet of
28
railroad tank cars with a combined carrying capacity of
564,000
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.The unique solution is
x1=
x2=
and
x3=
(Simplify your answers.)There are multiple possible combinations of how the tank cars should be leased. The combinations are obtained from the equations
x1= t+( ),
x2= t+( ),
and
x3=t
for
≤t≤ .
(Simplify your answers. Type integers or simplified fractions.)
There is no solution.
