If you sell a commodity at a fixed price, you can get a profit of 45 yuan per unit. Now you can get the same profit if you sell 8 units at a 25% discount as if you sell 12 units at a 35 yuan discount______ Yuan

Let the cost price of this commodity be x yuan, and the equation can be obtained as follows: (x + 45) × 85% × 8-8x = (45-35) × 12 & nbsp; & nbsp; & nbsp; (x + 45) × 6.8-8x = 10 × 12, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 6.8x + 306-8x = 120, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp
