Solving this equation is 3400/2x-16000/x =100.
It is verified that X = 100 is the root of the original equation, which accords with the meaning of the question.
=200,
∴ 100+200=300.
A: The mall bought 300 pieces of this electronic product twice.
(2) Assuming that the price of each electronic product in the shopping mall is Y yuan,
∵ The first batch of products * * * sold 100/ 10= 10 days,
The second batch of products will take 200/( 10-2) days to sell.
From the meaning of the title, it means 300 y-16000-34000-10× 60-25× 60 ≥ (16000+34000 )× 20/100.
Solve this inequality to get Y≥207.
A: The price of each electronic product in this mall is at least 207 yuan.
