Calculation of the Album Price in March

To calculate the price of the album in March, we need to consider the given information. The price of the album increased by 20% in April compared to March, and then decreased by 10% in May compared to April.

Let's assume the price of the album in March is x.

In April, the price increased by 20%, so the new price can be calculated as: x + 0.2x = 1.2x

In May, the price decreased by 10% compared to April, so the new price can be calculated as: 1.2x - 0.1(1.2x) = 1.2x - 0.12x = 1.08x

Given that the album price in May is 2700, we can set up the equation: 1.08x = 2700

Now we can solve for x to find the price of the album in March.

Calculating the value of x: 1.08x = 2700 x = 2700 / 1.08 x ≈ 2500

Therefore, the price of the album in March was approximately 2500 rubles.
