Answer 3

Problem Analysis

We are given the information that 3 identical pens and 5 identical pencils were purchased for a total of 52 rubles. Each pen costs 4 rubles. We need to determine the cost of one pencil.

Solution

Let's assume the cost of one pencil is x rubles.

The total cost of 3 pens is 3 * 4 = 12 rubles.

The total cost of 5 pencils is 5 * x = 5x rubles.

According to the given information, the total cost of 3 pens and 5 pencils is 52 rubles.

Therefore, we can write the equation:

12 + 5x = 52

To find the value of x, we can solve this equation.

Solving the Equation

12 + 5x = 52

Subtract 12 from both sides:

5x = 52 - 12

5x = 40

Divide both sides by 5:

x = 40 / 5

x = 8

Answer

Therefore, the cost of one pencil is 8 rubles.
