Problem Analysis

We are given that 3 éclairs and 5 cupcakes were purchased for a total of 495 rubles. It is also mentioned that éclairs are 34 rubles more expensive than cupcakes. We need to determine the cost of each type of pastry.

Solution

Let's assume the cost of a cupcake is x rubles. Since éclairs are 34 rubles more expensive than cupcakes, the cost of an éclair would be x + 34 rubles.

According to the given information, 3 éclairs and 5 cupcakes were purchased for a total of 495 rubles. We can set up the following equation to represent this information:

3 * (x + 34) + 5 * x = 495

Simplifying the equation:

3x + 102 + 5x = 495 8x + 102 = 495 8x = 495 - 102 8x = 393 x = 393 / 8 x = 49.125

Therefore, the cost of each cupcake is approximately 49.125 rubles and the cost of each éclair is approximately 83.125 rubles.

Answer

The cost of each cupcake is approximately 49.125 rubles and the cost of each éclair is approximately 83.125 rubles.
