An auto manufacturer sends cars from its two plants, Plant I and Plant II, to two delearships, dealership A and delearship B. Plant I ships 85 cars to the delearships and Plant II ships 70 cars. Dealership A needs 53 cars and dealership B needs 102 cars. The cost for shipping a car from Plant I to dealerships A and B is $310 and $220, respectively. The cost for shipping a car from Plant II to dealerships A and B is $330 and $150, respectively. There are $35050 available for shipping the cars.
Let x represent the number of
cars shipped from Plant I to dealership A. Let y represent the
number of cars shipped from Plant II to dealership A. Let z
represent the number of cars shipped from Plant I to dealership B.
Let w represent the number of cars shipped from Plant II to
dealership B.
Consider the equations
equation 1
equation 2
equation 3
equation4
equation5
(Equation 4)-(equation 1)
equation a
(equation 3)-(equation1)
equation b
consider equation 5
substitute
and
equation 6
consider equatioequn 1
multiplying this equation by 46 gives
equation 7
(equation 6)-(equation 7)
y is the number of cars shipped from plant II to dealership A
Substitute y=12 in equation 1
x+y=53
x+12=53
x=53-12
x=41
x is the number of cars shipped from plant I to dealership A
Therefore 41 cars are shipped from plant I to dealership A
Substitute x=41 in equation 3
x+z=85
41+z=85
z=85-41
z=44
z represent number of cars shipped from plant I to dealership B
Therefore 44 cars are shipped from plant I to dealership B
Substitute z=44 in equation 2
z+w=102
44+w=102
w=102-44
w=58
Number of cars shipped from plant II to dealership B is 58

Jones company has two manufacturing plants A and B, and three warehouses, W1, W2, W3. Each week Jones ships product from the plants to the warehouses. The system is balanced: A produces 500 units of product and B produces 300 units of product. Warehouse W1 needs 200 units of product, W2 needs 300 units of product, and W3 needs 300 units of product. Thus, over the entire system, there are 800 units produced by the two plants and 800 units...
Consider a system of two toy rail cars (i.e.. frictionless masses)- Suppose that car 1 has mass 6 kg and is traveling at 3 m/s toward the other car- Suppose car 2 has mass 3 kg and is moving toward the other car at 9 m/s. There is a bumper on the second rail car that engages at the moment the cars hit and does not let go (it connects the two cars). The bumper acts as a spring with...
