Answer 2

Calculating the Cost of Coffee

To calculate the cost of one portion of coffee, we can use the given prices for the ingredients.

- Price of 500g Ground Coffee: 150 rubles - Price of Sugar: 28 rubles per kg - Price of 1000 cubic cm of Cream: 22 rubles

Using the given quantities for one portion of coffee: - Ground Coffee: 10g - Sugar: 5g - Cream: 50 cubic cm

We can calculate the cost for each ingredient: 1. Cost of Ground Coffee: - Cost of 10g = (150 rubles / 500g) * 10g = 3 rubles 2. Cost of Sugar: - Cost of 5g = (28 rubles / 1000g) * 5g = 0.14 rubles 3. Cost of Cream: - Cost of 50 cubic cm = (22 rubles / 1000 cubic cm) * 50 cubic cm = 1.1 rubles

Adding these costs together gives the total cost for one portion of coffee.

Calculating the Cost of an Omelet

Similarly, we can calculate the cost of one portion of omelet using the given prices for the ingredients.

- Price of 10 Eggs: 25 rubles - Price of Milk: 18 rubles per kg - Price of Salt: 8 rubles per kg

Using the given quantities for one portion of omelet: - Eggs: 9 - Milk: 100g - Salt: 10g

We can calculate the cost for each ingredient: 1. Cost of Eggs: - Cost of 9 eggs = 25 rubles 2. Cost of Milk: - Cost of 100g = (18 rubles / 1000g) * 100g = 1.8 rubles 3. Cost of Salt: - Cost of 10g = (8 rubles / 1000g) * 10g = 0.08 rubles

Adding these costs together gives the total cost for one portion of omelet.

Calculating the Number of Omelet Portions

To find out how many portions of omelet can be prepared with 121 rubles and 90 kopecks, we can divide the total budget by the cost of one portion of omelet.

After calculating the cost of one portion of omelet, we can then divide the total budget by this cost to find out how many portions can be prepared.

Let's calculate the total cost of one portion of omelet and then find out how many portions can be prepared with the given budget.
