If a commodity is sold at a fixed price, it will get a profit of 45 yuan per unit. Now, the profit from selling 8 units at a 25% discount is the same as the profit from selling 12 units at a 35 yuan discount. How much is the price of this commodity?

According to the price of 35 yuan each sale can get a profit of 45-35 = 10 yuan, sell 12 can get a profit of 10 * 12 = 120 yuan; then according to the price of 15% discount to sell 8 profit is 120 yuan, each get a profit of 120 / 8 = 15 yuan; according to the price of 45 yuan each can get a profit, after 15% discount each can get a profit of 15 yuan
