The key point of this topic is "Please design an optimal transportation scheme for this big lemon family"
The best plan is! ! Solution:
Because there are 62 tons of lemons, if you use a truck with 10 tons, you must transport it seven times, because the last trip can only transport 2 tons of goods, which is not the best solution. The seventh transportation is X200, and X is 10% off (0.9)= 1260 yuan!
It must be 16 times, 16 times, X90 yuan, 15% discount (0.85)= 1224 yuan to transport a 4-ton minivan.
At first glance, a minivan is the best solution.
However, neither scheme is the best, because the last car is not full of goods, but it must pay a freight.
Therefore, the best solution can only be the cooperative transportation of large trucks and small trucks. For the sake of trucks, the final transportation will not be wasted. So 62 tons of lemons are distributed like this! The truck is 50 tons, and the truck 12 tons, so the truck is transported five times and the truck is transported three times!
So the final best solution is:
Truck: 50/ 10X200X0.9=900 yuan,
Minivan: 12/4x 9x 0.85 = 229.5 yuan.
The best scheme is, 900+229.5= 1 129.5 yuan!
This is the final answer. If the answer is correct, you should give points! ! ! ! ! ! ! ! ! ! Typing is very hard, with analysis! ! !
