Problem Analysis

To find the total cost of the purchase, we need to calculate the cost of the red balloons and the cost of the blue balloons separately, and then add them together.

Calculation

Let's calculate the cost of the red balloons first. We know that the price of a red balloon is 27 rubles, and we have bought 50 red balloons. Therefore, the cost of the red balloons is 50 * 27 = 1350 rubles.

Next, let's calculate the cost of the blue balloons. We are given that the price of a blue balloon is 7 rubles more than the price of a red balloon. Therefore, the price of a blue balloon is 27 + 7 = 34 rubles. We have bought 35 blue balloons, so the cost of the blue balloons is 35 * 34 = 1190 rubles.

Finally, we can find the total cost of the purchase by adding the cost of the red balloons and the cost of the blue balloons: 1350 + 1190 = 2540 rubles.

Therefore, the total cost of the purchase is 2540 rubles.

Answer

The total cost of the purchase, considering the given prices and quantities, is 2540 rubles.
