Question

Для приготовления одной порции омлета нужно взять 9 яиц 100 гр молока и 10 гр соли .Десяток яиц стоит 25 руб цена молока 18 руб цена соли 8 руб .Сколько порции омлета можно приготовить на 121р 90 коп ?"

Answer 1

Цена за 9 яиц=25/10*9=22,5 руб
Цена за 100 гр молока=18*100/1000=1,8 рублей
Цена за 10 гр соли=8*10/1000=0,08 рублей
Итого цена за 1 омлет=22,5+1,8+0,08=24,38 руб
121,90/24,38=5 порций

Answer 2

Calculating the Number of Omelet Portions

To calculate the number of omelet portions that can be prepared with the given budget, we can use the prices of the eggs, milk, and salt to determine the maximum number of portions that can be made within the budget.

The cost of the ingredients is as follows: - 10 eggs cost 25 rubles - 100g of milk costs 18 rubles - 10g of salt costs 8 rubles

Cost of Ingredients

Let's calculate the cost of the ingredients for one portion of omelet: - Cost of 1 egg = 25 rubles / 10 eggs = 2.5 rubles per egg - Cost of 100g of milk = 18 rubles - Cost of 10g of salt = 8 rubles

Calculating the Total Cost per Portion

The total cost of the ingredients for one portion of omelet can be calculated by adding the individual costs of the eggs, milk, and salt.

- Total cost per portion = (Cost of 1 egg) * 9 + (Cost of 100g of milk) + (Cost of 10g of salt)

Solution

Let's calculate the total cost per portion and then determine the maximum number of portions that can be prepared with the given budget of 121 rubles and 90 kopecks.

The total cost per portion is: - Total cost per portion = (2.5 * 9) + 18 + 8 = 22.5 + 18 + 8 = 48.5 rubles

Maximum Number of Portions

Now, we can calculate the maximum number of portions that can be prepared with the given budget: - Maximum number of portions = Budget / Total cost per portion - Maximum number of portions = 121.90 / 48.5 ≈ 2.51

Therefore, with 121 rubles and 90 kopecks, it is possible to prepare approximately 2 portions of omelet.
