Answer 2

Calculation of Expenses and Savings

To calculate the amount spent on each category of expenses and the amount left for savings, we can use the given percentages and the total monthly income of Nikita's family, which is 5750 rubles.

a) Calculation of Expenses: - Utility expenses: 6.7% of the total income - Telephone expenses: 0.9% of the total income - Food expenses: 30.4% of the total income - Clothing expenses: 23.5% of the total income

To find the amount spent on each category, we can multiply the respective percentages by the total income:

- Utility expenses: 5750 * 6.7% = 385.25 rubles - Telephone expenses: 5750 * 0.9% = 51.75 rubles - Food expenses: 5750 * 30.4% = 1752 rubles - Clothing expenses: 5750 * 23.5% = 1351.25 rubles

b) Calculation of Savings: To find the amount left for savings, we need to subtract the sum of all expenses from the total income:

Total expenses = Utility expenses + Telephone expenses + Food expenses + Clothing expenses

Total expenses = 385.25 + 51.75 + 1752 + 1351.25 = 3540.25 rubles

Amount left for savings = Total income - Total expenses

Amount left for savings = 5750 - 3540.25 = 2210.75 rubles

Therefore, the answers to the given questions are: a) The amount spent on each category of expenses is as follows: - Utility expenses: 385.25 rubles - Telephone expenses: 51.75 rubles - Food expenses: 1752 rubles - Clothing expenses: 1351.25 rubles

b) The amount left for savings, which will be used for the vacation, is 2210.75 rubles.

Please note that these calculations are based on the given percentages and total income.
