There is a certain company at the railway station, and there is a ticket to which railway station in

Set up a type A cargo box x to transport class A goods, B type cargo (50-x) to save class A goods, get 35X+25 (50-X) 1530

15x+35(50-x)≥1150

Solving inequalities yields 28 x 30

Therefore, there are three schemes: with 28 sections of type A cargo boxes and 22 sections of type B cargo boxes, with 29 sections of type A cargo boxes and 21 sections of type B cargo boxes, with 30 sections of type A cargo boxes and 20 sections of type B cargo boxes, set the total freight of w million yuan, arrange type A cargo box X section to transport type A goods, type B cargo box (50-x) section of class A goods, to.

w= (x takes ).

This is a one-time function, k=, so w decreases as x increases, and when x=30, w is the smallest =

A: The least freight is charged with 30 knots of type A and 20 knots of type B containers. The minimum shipping fee is $310,000.

Solve the A type of carriage x cars; then B type car (50-x) units.

35x+25 (50-x) less than or equal to 1530 (1) 15x+35 (50-x) less than or equal to 1150 (2) from one x less than or equal to 20

x from two is greater than or equal to 30 cars.

28 is less than or equal to x less than or equal to 30 from one to two

Because x is an integer, x can be taken 28---29---30 There are 3 schemes.

1: Arrangement A type 28; Type B 22

2：a29；b21

3: Type A 30; Type B 20

I played very hard and gave me points.

1.From the point of view of the topic, B cargo can only be transported in type A carriages, so 77 type A carriages are required to load B goods first.

2.Cargo A can be loaded into 77 A-type carriages.

Therefore, a total of 77 A-type cars are required. The fee is 10,000 yuan.

That's the only option.

PS: I think there may be a condition missing, Class B cargo xx tons can fill a type B car.
