Answer 2

Calculation of the Number of Calendars Purchased by Olesya

To determine the number of calendars purchased by Olesya, we can set up a proportion based on the prices paid by both Yulia and Olesya.

Let's denote the number of calendars purchased by Olesya as x.

According to the given information: - Yulia paid 18 rubles for 10 calendars. - Olesya paid 12 rubles for x calendars.

We can set up the following proportion:

18 rubles / 10 calendars = 12 rubles / x calendars

To solve for x, we can cross-multiply and solve the resulting equation:

18 rubles * x calendars = 12 rubles * 10 calendars

Simplifying the equation:

18x = 120

Dividing both sides of the equation by 18:

x = 120 / 18

Evaluating the division:

x ≈ 6.67

Since we cannot have a fraction of a calendar, we can round the result to the nearest whole number. Therefore, Olesya purchased approximately 7 calendars.

Please note that the given information does not specify whether the number of calendars purchased should be a whole number or not. Rounding the result is an assumption made based on common practice.
