Сразу после десятой яблони память на телефоне Маши закончилась, и девочка не смогла сфотографировать оставшиеся 13 деревьев.

0 шаг x = 17 + 18 x = 10 + 13 + 8

1 шаг x = 35 листов x = 23 + 8 листов

2 шаг x = 35 листов x = 31 лист

3 шаг x = 35 35 = 31

4 шаг x = 35 35/31 = 1

x = 35 листов

Problem Analysis

In this problem, we are given that there are 17 apple trees and 15 poplar trees along a road connecting the houses of Masha and Sasha. Masha takes photos of all the trees while walking to Sasha's house, but her phone's memory runs out after the tenth apple tree, so she cannot photograph the remaining 13 trees. The next day, Sasha goes to Masha's house and plucks one leaf from each tree, starting from the eighth apple tree. We need to determine how many leaves Sasha plucked.

Solution

To solve this problem, we need to calculate the number of trees that Masha was able to photograph and subtract it from the total number of trees to find the number of trees that Sasha plucked leaves from.

Let's calculate the number of trees that Masha photographed: - Masha photographed all the trees until her phone's memory ran out after the tenth apple tree. - Since there are 17 apple trees and 15 poplar trees, Masha photographed a total of 10 apple trees and 15 - 10 = 5 poplar trees.

Now, let's calculate the number of trees that Sasha plucked leaves from: - Sasha started plucking leaves from the eighth apple tree. - Since there are 17 apple trees, Sasha plucked leaves from 17 - 8 + 1 = 10 apple trees.

Therefore, Sasha plucked leaves from a total of 10 apple trees.

Answer

Sasha plucked leaves from 10 trees.

Explanation

Masha photographed a total of 10 apple trees and 5 poplar trees before her phone's memory ran out. Sasha plucked leaves from 10 apple trees starting from the eighth apple tree.
