Problem Analysis

The problem states that the buyer paid 420 rubles for the delivery of a bookshelf, which is 3% of the bookshelf's cost. We need to determine the cost of the bookshelf.

Solution

Let's assume the cost of the bookshelf is x rubles.

According to the problem, the buyer paid 420 rubles for delivery, which is 3% of the bookshelf's cost. We can express this information in the equation:

0.03 * x = 420

To find the value of x, we can divide both sides of the equation by 0.03:

x = 420 / 0.03

Now, let's calculate the value of x:

x = 420 / 0.03 = 14,000

Therefore, the cost of the bookshelf is 14,000 rubles.

Answer

The bookshelf cost 14,000 rubles.
