Answer 2

Calculation of Omelette Portions

To calculate the number of omelette portions that can be prepared with a given budget of 121 rubles and 90 kopeks, we need to determine the cost of the required ingredients and then divide the total budget by the cost per portion.

Let's calculate the cost of the ingredients first:

- The cost of 9 eggs is 9/10 * 25 rubles = 22.50 rubles. - The cost of 100 grams of milk can be calculated by converting it to kilograms (0.1 kg) and then multiplying it by the cost per kilogram, which is 18 rubles. So, the cost of 100 grams of milk is 0.1 * 18 = 1.80 rubles. - The cost of 10 grams of salt can be calculated in the same way. Converting it to kilograms (0.01 kg) and multiplying it by the cost per kilogram, which is 8 rubles, gives us the cost of 10 grams of salt as 0.01 * 8 = 0.08 rubles.

Now, let's calculate the total cost of one portion of omelette:

- Total cost = cost of eggs + cost of milk + cost of salt = 22.50 + 1.80 + 0.08 = 24.38 rubles.

Finally, we can calculate the number of omelette portions that can be prepared with the given budget:

- Number of portions = total budget / cost per portion = (121 rubles + 0.90 kopeks) / 24.38 rubles = 4 portions.

Therefore, with a budget of 121 rubles and 90 kopeks, you can prepare approximately 4 portions of omelette.
