A commodity is ready to be sold at a discount due to the change of season. If it is sold at a 7.5% discount, it will lose 25 yuan. If it is sold at a 10% discount, it will earn 20 yuan. So we need to determine the price of the commodity

0.75X+25=0.9X-20
X = 300 yuan

A certain commodity is ready to be sold at a discount in the new season. If it is sold at a discount of 7.5% of the bid price, it will lose 25 yuan, and if it is sold at a 10% discount, it will make 20 yuan Q: the price of this product is fixed It's better to solve the equation

Let the price of this commodity be x yuan
If it is sold at a discount of 7.5% of the bid price, it will lose 25 yuan, and the cost will be 0.75x + 25 yuan;
The cost is 0.9x-20 yuan if it is sold at 10% discount of the bid price;
The equation is: 0.75x + 25 = 0.9x-20,
The solution is: x = 300,
That is: the price of this commodity is 300 yuan
