Calculation of the Cost of One Pencil

To find the cost of one pencil, we can use the given information about the cost of three identical pens and five identical pencils.

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

According to the given information: - The cost of three identical pens is 4 rubles each, so the total cost of three pens is 3 * 4 = 12 rubles. - The cost of five identical pencils is x rubles each, so the total cost of five pencils is 5 * x = 5x rubles.

The total cost of three pens and five pencils is given as 52 rubles.

Therefore, we can set up the equation: 12 + 5x = 52

To solve for x, we can subtract 12 from both sides of the equation: 5x = 52 - 12 5x = 40

Finally, we can divide both sides of the equation by 5 to find the value of x: x = 40 / 5 x = 8

Therefore, the cost of one pencil is 8 rubles.
