Problem:

Для детского сада купили 7 мячей по 55 рублей каждый и 7 пирамидок по 36 рублей каждая. Сколько стоит вся покупка?

Solution 1:

To find the total cost of the purchase, we can calculate the cost of the balls and the cost of the pyramids separately, and then add them together.

The cost of the balls can be calculated by multiplying the number of balls (7) by the cost of each ball (55 rubles): Cost of balls = 7 * 55 = 385 rubles.

The cost of the pyramids can be calculated by multiplying the number of pyramids (7) by the cost of each pyramid (36 rubles): Cost of pyramids = 7 * 36 = 252 rubles.

Finally, we can find the total cost of the purchase by adding the cost of the balls and the cost of the pyramids together: Total cost of the purchase = Cost of balls + Cost of pyramids = 385 + 252 = 637 rubles.

Therefore, the total cost of the purchase for the balls and pyramids is 637 rubles.

Solution 2:

Alternatively, we can find the total cost of the purchase by first calculating the cost of one ball and one pyramid, and then multiplying them by the respective quantities.

The cost of one ball is 55 rubles, and there are 7 balls: Cost of balls = 55 * 7 = 385 rubles.

The cost of one pyramid is 36 rubles, and there are 7 pyramids: Cost of pyramids = 36 * 7 = 252 rubles.

Again, we can find the total cost of the purchase by adding the cost of the balls and the cost of the pyramids together: Total cost of the purchase = Cost of balls + Cost of pyramids = 385 + 252 = 637 rubles.

So, the total cost of the purchase for the balls and pyramids is 637 rubles.

Conclusion:

In conclusion, the total cost of the purchase for 7 balls priced at 55 rubles each and 7 pyramids priced at 36 rubles each is 637 rubles.
