Answer 2

Calculation of the Original Price

To calculate the original price of the refrigerator before the price increase, we can use the information provided. We know that the price after the increase is 13,800 rubles, and the increase was 15%.

Let's denote the original price as x. We can set up the following equation to solve for x:

x + 15% of x = 13,800

To solve this equation, we need to find 15% of x and add it to x:

x + 0.15x = 13,800

Combining like terms:

1.15x = 13,800

Now, we can solve for x by dividing both sides of the equation by 1.15:

x = 13,800 / 1.15

Evaluating the expression:

x ≈ 12,000

Therefore, the original price of the refrigerator before the price increase was approximately 12,000 rubles.

Answer

The refrigerator cost approximately 12,000 rubles before the price increase.
