In order to expand its business, a company decided to buy six machines to produce a live race. Now there are two options, A and B. The price of each machine and the number of pistons produced by each machine are shown in the following table. After the budget, the funds for purchasing the machine this time can't exceed 340,000 yuan.

table

Machine types a and b

Price, 10,000 yuan, 7.5 yuan in Taiwan Province.

Monthly daily output (unit) 100 60

question

(1_) There are several purchase schemes according to the requirements of this company.

(2) If the daily output of the six machines purchased by the company can not be less than 380 pistons, which purchasing scheme should be chosen to save money?

If you buy X machines of Class A, you will buy (6-X) machines of Class B..

7X+5(6x)= 0.5

Therefore, only Scheme 2 and Scheme 3 meet the requirements.

Fund =7X+5(6-X)=7X+30-5X=2X+30.

So the smaller the value of x, the less money.

So choose option two to save money.

Answer: Option 2 saves money: A buys 1 and B buys 5.
