After the 5.12 Wenchuan earthquake, does Japan have money and material to help China?

Not only the Japanese government, but also non-governmental organizations and enterprises organized a lot of fund-raising activities

On May 12, a 8.0 magnitude earthquake occurred in Wenchuan County, Sichuan Province, China
After the disaster, teachers and students of our school, together with the people of the whole country, quickly gave a helping hand and decided to donate 60 bedsteads and 100 sets of desks and stools to the disaster area. Now we plan to rent eight trucks of a and B to transport these materials to the disaster area. It is known that a truck of a can hold 5 bedsteads and 20 sets of desks and stools, and a truck of B can hold 10 bedsteads and 1 set of desks and stools
(1) How can the school arrange a and B trucks to transport materials to the disaster area at one time? How many plans are there?
(2) If a truck costs 1200 yuan per vehicle and B truck costs 1000 yuan per vehicle, which scheme should the school choose? At least how much?

There are x vehicles for vehicle a and 8-x vehicles for vehicle B
According to the equation of bed carrier quantity: 5x + (8-x) * 10 = 60
The solution is x = 4, that is to say, there are 4 cars a and 4 cars B
Transportable: bed frame 5 * 4 + 10 * 4 = 60, desk stool 20 * 4 + 10 * 4 = 120 sets, meet the requirements
According to the table stool quantity equation: 20x + (8-x) * 10 = 100
The solution is x = 2, that is to say, there are 2 cars a and 6 cars B
Transportable: bed frame 5 * 2 + 10 * 6 = 70, desk stool 20 * 2 + 10 * 6 = 100 sets, meet the requirements
Compared with the transportation cost of the two schemes, the cost of more B cars is less, so the school should rent two a cars and six B cars, the total cost: 1200 * 2 + 1000 * 6 = 8400 yuan
