1862-1302=560грн- заплатили за ботики
560:70=8пар - купили ботинок
Ответ: 8 пар

Answer 2

Узнаем сколько запалили за 7 пар по 186 гр. 7х186=1302. Значит за другие пары по 70 гривен заплатили: 1862-1302=560. Мы знаем что каждая пара стоит 70 гр, значит кол-во пар равно: 560:70=8. Значит 7 пар по 186 гр и 8 пар по 70 гр. 7+8=15
Ответ: 15

Problem Analysis

To solve this problem, we need to determine the number of pairs of boots that were purchased. We are given the following information: - 7 pairs of shoes were purchased at a price of 186 UAH per pair. - Several pairs of boots were purchased at a price of 70 UAH per pair. - The total amount paid was 1862 UAH.

Let's assume that the number of pairs of boots purchased is represented by the variable 'x'.

Solution

To find the number of pairs of boots purchased, we can set up the following equation based on the given information:

7 * 186 + x * 70 = 1862

Simplifying the equation, we have:

1302 + 70x = 1862

Subtracting 1302 from both sides of the equation, we get:

70x = 560

Dividing both sides of the equation by 70, we find:

x = 8

Therefore, 8 pairs of boots were purchased.

Answer

The number of pairs of boots purchased is 8.
