Excuse me, how to do the second small question? With the continuous growth of railway passenger traffic, Chongqing North Railway Station is becoming more and more crowded. In order to satisfy the railway traffic, Solution: It takes X months for Team A to complete it alone, and (x-5) months for Team B to complete it alone.

From the meaning of the question, x(x-5)=6(x+x-5),

The solution is x 1= 15, x2=2 (irrelevant, omitted).

Then x-5= 10.

A: It takes 65,438+05 months for Team A to complete this project alone, and 65,438+00 months for Team B to complete this project alone;

(2) If Team A sets to work for y months, Team B will work for 1/2y months.

Judging from the meaning of the question,100y+(100+50) y/2 ≤1500,

For solving inequalities, y≤8.57,

The construction time is in months,

∴y≤8，

Answer: It will take Team A eight months at most to complete this project, so that the project cost will not exceed150,000 yuan.
