Answer 2

Problem Statement:

In a stationery store, a notebook with grid lines costs 4 rubles, an album costs 1 ruble more than the notebook, and a pen costs 4 rubles less than the album. How much does each item cost?

Solution:

Let's assign variables to represent the cost of each item: - Let N be the cost of the notebook. - Let A be the cost of the album. - Let P be the cost of the pen.

Based on the given information, we can write the following equations: 1. The cost of the album is 1 ruble more than the notebook: A = N + 1. 2. The cost of the pen is 4 rubles less than the album: P = A - 4.

To solve the problem, we need to find the values of N, A, and P.

Solution Steps:

To solve the problem using two actions, we can follow these steps:

Action 1: 1. Assign a variable to represent the cost of the notebook: N = x. 2. Use the equation A = N + 1 to find the cost of the album in terms of x: A = x + 1. 3. Use the equation P = A - 4 to find the cost of the pen in terms of x: P = (x + 1) - 4.

Action 2: 4. Substitute the value of P from step 3 into the equation P = (x + 1) - 4 to solve for x. 5. Substitute the value of x into the equations A = x + 1 and P = (x + 1) - 4 to find the values of A and P.

Let's solve the problem using these steps.

Action 1:

1. Let N = x be the cost of the notebook. 2. The cost of the album is A = N + 1 = x + 1. 3. The cost of the pen is P = A - 4 = (x + 1) - 4.

Action 2:

4. Substitute the value of P from step 3 into the equation P = (x + 1) - 4: - (x + 1) - 4 = x - 3.

5. Substitute the value of x into the equations A = x + 1 and P = (x + 1) - 4: - A = (x + 1) = (x - 3) + 1 = x - 2. - P = (x + 1) - 4 = (x - 3) - 4 = x - 7.

Therefore, the cost of the notebook is N = x, the cost of the album is A = x - 2, and the cost of the pen is P = x - 7.

Conclusion:

In conclusion, the cost of the notebook is x rubles, the cost of the album is x - 2 rubles, and the cost of the pen is x - 7 rubles.
