Answer 1

1) 150 - 120 = 30 манатов настолько понизилась цена

Answer 2

Calculation of Price Change Percentage

To calculate the percentage change in the price of the dress, we can use the following formula:

Percentage Change = ((New Price - Old Price) / Old Price) * 100

Given that the old price of the dress was 150 manats and the new price is 120 manats, we can substitute these values into the formula:

Percentage Change = ((120 - 150) / 150) * 100

Calculating this expression, we find that the percentage change in the price of the dress is approximately -20%.

Please note that the negative sign indicates a decrease in price.
