Lingling's family is going to decorate the new house. If the two decoration companies cooperate, it will take 6 weeks to complete, and the total decoration cost is 52,000 yuan. If company a does it alone for 4 weeks, the rest will be done by. 1) Party A completes X every week and Party B completes Y every week.

Simultaneous equations: 6x+6y = 1——————①

4x+9y = 1—————②

X = 1/ 10，Y = 1/ 15。

That is, it takes 10 week for A to complete alone, and 15 week for B to complete alone.

Therefore, from the perspective of saving time, we should choose Company A..

2) Party A charges 10000 yuan per week, and Party B charges 10000 yuan per week.

Simultaneous equation: 6a+6b = 5.2 ——————————— ① ①.

4a+9b = 4.8—————②

The solution is a = 6/65438+ 10,000 yuan, and b = 4/ 1.5 million yuan.

Multiply it by the time they need.

Answer: 6/10×10 = 60,000 yuan.

B: 4/15×15 = 40,000 yuan.

Therefore, from the perspective of saving money, we should choose company B.
