Calculate the Final Price: Air Conditioner’s Cost After 10% Increase and 15% Decrease

To solve this problem, we will walk through each step sequentially:

• Step 1: Calculate the price after a 10% increase.

• Step 2: Calculate the price after a 15% decrease from the increased price.

Now, let's work through these steps:
Step 1: The original price of the air conditioner is \2500 \). When the price is increased by 10%, the new price is calculated as follows: $\text{New price after 10\% increase} = 2500 \times \left(1 + \frac{10}{100}\right) = 2500 \times 1.10 = 2750$

Step 2: This increased price of \$2750 is then decreased by 15\text{Final price after 15\% decrease} = 2750 \times \left(1 - \frac{15}{100}\right) = 2750 \times 0.85 = 2337.5$

Therefore, the price of the air conditioner at the end of the season is $2337.5$ dollars.
