Answer 2

Calculating the Original Price of the Jacket

To calculate the original price of the jacket, we can use the information provided about the percentage decrease and the resulting price.

Let's denote the original price of the jacket as x.

After a 10% decrease, the price becomes 90% of the original price: 0.9x. After a 15% decrease, the price becomes 85% of the previous price: 0.85 * 0.9x.

Given that the resulting price is 1530 rubles, we can set up the equation: 0.85 * 0.9x = 1530.

Solving for the Original Price

To find the original price of the jacket, we can solve the equation: 0.85 * 0.9x = 1530.

First, we calculate 0.85 * 0.9: 0.85 * 0.9 = 0.765.

Then, we can solve for x: 0.765x = 1530.

Dividing both sides by 0.765: x = 1530 / 0.765.

Calculating the Original Price

Calculating the original price of the jacket: x = 2000 rubles.

Therefore, the original price of the jacket was 2000 rubles.
