Answer 2

Calculation of the Change in the Preliminary Price

To calculate the change in the preliminary price after it was first increased by 10% and then decreased by 15%, we can follow these steps:

1. Start with the original preliminary price. 2. Increase the preliminary price by 10%. 3. Decrease the increased price by 15%.

Let's assume the original preliminary price is $100.

Calculation:

1. Increase the preliminary price by 10%: - $100 + (10% of $100) = $100 + $10 = $110.

2. Decrease the increased price by 15%: - $110 - (15% of $110) = $110 - $16.50 = $93.50.

Therefore, the preliminary price changed from $100 to $93.50, which represents a decrease of approximately 6.5%.

Please note that the above calculation assumes a linear change in the price. If there are any additional factors or conditions that may affect the calculation, please provide more information for a more accurate response.
