Problem:

The original price of hockey skates was 4500 rubles. The price was first reduced by 20%, and then the reduced price was increased by 20%. What is the final price of the skates after the price increase?

Solution:

To find the final price of the skates after the price increase, we need to follow these steps:

1. Calculate the price after the initial reduction of 20%. 2. Calculate the price after the subsequent increase of 20%.

Let's calculate each step:

1. Initial reduction of 20%: - To find the price after a 20% reduction, we can multiply the original price by (100% - 20%) or 0.8. - 4500 * 0.8 = 3600 rubles.

2. Subsequent increase of 20%: - To find the price after a 20% increase, we can multiply the reduced price by (100% + 20%) or 1.2. - 3600 * 1.2 = 4320 rubles.

Therefore, the final price of the hockey skates after the price increase is 4320 rubles.
