Question

Зарплата папы 1,5 раза больше мамы,40%дохода тратится на покупки.Остальная часть на одежду и банк. Зарплата мамы увеличилась на 25%,а зарплата папы и текущие расходы остались прежние.Как изменилась доля прочих покупок в бюджете семьи?помогииите

Answer 1

1- зарплата мамы
1*1,5=1,5 зарплата папы
1+1,5=2,5 зарплата обоих родителей
2,5:100*40=1 тратится на покупки (можно сделать вывод что зп мамы составляет 40% и тратится на покупки). соответственно зп папы тратится на все остальное
1:100*(100+25)=1,25 составляет зп мамы 
1,25+1,5=2,75 зарплата обоих родителей
2,75:100=0,0275 составит 1% от зп обоих родителей
1:0,0275=36,36 % составит трата на покупки и
1,5:0,0275=54,55% составят затраты на прочие расходы
можно сделать вывод что траты уменьшились

Calculation of Family Budget Changes

To determine how the proportion of other purchases in the family budget has changed, we need to analyze the given information.

Given: - The father's salary is 1.5 times higher than the mother's salary. - 40% of the income is spent on purchases. - The remaining portion is allocated to clothing and savings. - The mother's salary has increased by 25%. - The father's salary and current expenses remain the same.

Let's break down the steps to calculate the change in the proportion of other purchases in the family budget:

1. Calculate the original family budget: - Let's assume the mother's salary is M. - The father's salary is 1.5 times higher, so the father's salary is 1.5M. - The total income of the family is M + 1.5M = 2.5M. - 40% of the income is spent on purchases, which is 0.4 * 2.5M = M. - The remaining portion, which is allocated to clothing and savings, is 2.5M - M = 1.5M.

2. Calculate the new family budget after the mother's salary increase: - The mother's salary has increased by 25%, so her new salary is M + 0.25M = 1.25M. - The father's salary remains the same at 1.5M. - The total income of the family is now 1.25M + 1.5M = 2.75M. - 40% of the income is still spent on purchases, which is 0.4 * 2.75M = 1.1M. - The remaining portion, which is allocated to clothing and savings, is 2.75M - 1.1M = 1.65M.

3. Calculate the change in the proportion of other purchases: - The original portion allocated to other purchases was 1.5M. - The new portion allocated to other purchases is 1.65M. - The change in the proportion of other purchases is 1.65M - 1.5M = 0.15M.

Therefore, the change in the proportion of other purchases in the family budget is 0.15M.

Please note that the actual values for the salaries and budget portions were not provided in the question, so we used variables for calculations.
