Question

Линейка стоит m p., карандаш-на 1800р. меньше, а тетрадь вдвое дороже линейки. Сколько стоят линейка, карандаш и тетрадь вместе? Ответ запишите выражением, упростите и найдите его значение при m = 5000р

Answer 1

M-1800+(m-1800)*2+m
5000-1800+(5000-1800)*2+5000=14600 рублей
пояснение: 5000-1800=3200, 3200*2=6400, 3200+6400=9600, 9600+5000=14600 рублей

Answer 2

Problem Analysis

We are given the following information: - The price of a ruler is m p. - The price of a pencil is 1800 p less than the ruler. - The price of a notebook is twice the price of the ruler.

We need to find the total cost of the ruler, pencil, and notebook together.

Solution

Let's break down the problem step by step:

1. The price of the ruler is m p. 2. The price of the pencil is 1800 p less than the ruler. Therefore, the price of the pencil is (m - 1800) p. 3. The price of the notebook is twice the price of the ruler. Therefore, the price of the notebook is 2m p.

To find the total cost of the ruler, pencil, and notebook together, we add their prices:

Total cost = price of ruler + price of pencil + price of notebook

Total cost = m p + (m - 1800) p + 2m p

Simplifying the expression:

Total cost = m + m - 1800 + 2m

Total cost = 4m - 1800

Now, we can substitute the value of m with 5000 p and calculate the total cost.

Total cost = 4 * 5000 - 1800

Total cost = 20000 - 1800

Total cost = 18200 p

Therefore, the total cost of the ruler, pencil, and notebook together is 18200 p.

Answer

The total cost of the ruler, pencil, and notebook together is 18200 p.
