Problem Analysis

To determine if Olga can buy a pen and a pencil with her 60 rubles, we need to compare the prices of the pen, pencil, and notebook.

Given information: - The pen costs 27 rubles, which is 3 times more expensive than the pencil. - The notebook is 7 rubles cheaper than the pen.

Calculating the Prices

Let's calculate the prices of the pencil and notebook based on the given information.

1. The pen costs 27 rubles. 2. The pen is 3 times more expensive than the pencil. Therefore, the pencil costs 27 / 3 = 9 rubles. 3. The notebook is 7 rubles cheaper than the pen. Therefore, the notebook costs 27 - 7 = 20 rubles.

Can Olga Buy the Pen and Pencil?

Now, let's determine if Olga can buy the pen and pencil with her 60 rubles.

1. The pen costs 27 rubles. 2. The pencil costs 9 rubles. 3. Olga has 60 rubles.

To find out if Olga can buy both the pen and pencil, we need to calculate the total cost of the pen and pencil.

Total cost = pen cost + pencil cost = 27 + 9 = 36 rubles.

Since the total cost of the pen and pencil is 36 rubles, and Olga has 60 rubles, Olga can buy the pen and pencil with her 60 rubles.

Conclusion

Based on the given information, Olga can buy the pen and pencil with her 60 rubles.
