Problem Analysis

Ira and Vera bought 8 hair clips at the same price. Ira paid 27 rubles, and Vera paid 45 rubles. We need to find out how many hair clips each girl bought.

Solution

Let's denote the price of each hair clip as x. We know that Ira paid 27 rubles and Vera paid 45 rubles. We also know that the total number of hair clips they bought is 8.

Equations

We can set up the following equations based on the given information: 1. Ira's payment: 27 = 8 * x 2. Vera's payment: 45 = 8 * x

Solving for x

We can solve for x by dividing the total payment by the number of hair clips: 1. x = 27 / 8 2. x = 45 / 8

Let's calculate the value of x.

Calculation

- For Ira: - x = 27 / 8 - x = 3.375

- For Vera: - x = 45 / 8 - x = 5.625

Conclusion

Ira paid 27 rubles for 8 hair clips, which means each hair clip cost 3.375 rubles. Vera paid 45 rubles for 8 hair clips, which also means each hair clip cost 5.625 rubles.

Final Answer

Ira bought 8 hair clips at 3.375 rubles each, and Vera bought 8 hair clips at 5.625 rubles each.
