A shop bought 600 souvenirs, each of which was purchased in 6 yuan. In the first week, it sold 200 souvenirs at the price of 10 yuan, and in the second week, it sold at the price of 10 yuan.

Solution: The answer is: 200× (10-6)+(10-x-6) (200+50x)+[(4-6) (600-6).

That is 800+(4 ~ x) (200+50x) ~ 2 (200 ~ 50x) =1250,

Finishing: x2-2x+ 1 = 0,

Solution: x 1=x2= 1,

∴ 10﹣ 1=9,

The sales price for the second week is 9 yuan.
