Problem Analysis

The problem states that a group of artists traveled along the Golden Ring of Russia and made sketches in 4 cities. In each city, they used half of their available sheets of paper. After visiting the fourth city, they had 2 sheets of paper left. We need to determine how many sheets of paper the artists had before starting their work.

Solution

Let's assume that the number of sheets of paper the artists had before starting their work is represented by the variable x.

According to the problem, in each city, they used half of their available sheets of paper. So, after visiting the first city, they would have x/2 sheets of paper left. After visiting the second city, they would have (x/2)/2 = x/4 sheets of paper left. After visiting the third city, they would have (x/4)/2 = x/8 sheets of paper left. Finally, after visiting the fourth city, they had 2 sheets of paper left.

We can set up the following equation to solve for x:

x/8 = 2

To solve for x, we can multiply both sides of the equation by 8:

x = 2 * 8 = 16

Therefore, the artists had 16 sheets of paper before starting their work.

Answer

The artists had 16 sheets of paper before starting their work.
