Problem Analysis

We are given the following information: - Jen has 20 more marbles than Igor. - Jen has 15 fewer marbles than Petya.

We need to determine who has more marbles and by how much: Igor or Petya.

Solution

Let's assume that Igor has x marbles. According to the given information, Jen has 20 more marbles than Igor, so Jen has x + 20 marbles. Similarly, Jen has 15 fewer marbles than Petya, so Petya has x + 20 + 15 = x + 35 marbles.

To determine who has more marbles, we need to compare the number of marbles Jen has with the number of marbles Petya has.

If we compare x + 20 with x + 35, we can see that x + 35 is greater. Therefore, Petya has more marbles than Igor.

To find out how many more marbles Petya has, we subtract the number of marbles Igor has from the number of marbles Petya has:

Petya's marbles - Igor's marbles = (x + 35) - x = 35.

Therefore, Petya has 35 more marbles than Igor.

Answer

Based on the given information, Petya has more marbles than Igor, and Petya has 35 more marbles than Igor.
