2) 4000 + 480 = 4480 руб. - цена в 2015

3) 4480 × 0.1 = 448руб - цена снова поднялась

4) 4480 + 448 = 4928 - цена в 2016

5) 4928 × 0.07 = 345руб. -цена поднялась

6) 4928 + 345 = 5273 руб - цена в 2017

Calculation of the Rent Increase

To calculate the rent increase for each year, we need to apply the percentage increase to the previous year's rent. Let's calculate the rent for each year based on the given information:

- In 2014, the family paid 4000 rubles per month for the apartment. - In 2015, the rent increased by 12%. To calculate the new rent, we multiply the previous year's rent by 1 + (12% / 100). - In 2016, the rent increased by 10%. Again, we multiply the previous year's rent by 1 + (10% / 100). - In 2017, the rent increased by 7%. We multiply the previous year's rent by 1 + (7% / 100).

Let's calculate the rent for each year:

- 2014: 4000 rubles per month - 2015: 4000 * (1 + (12% / 100)) = 4480 rubles per month - 2016: 4480 * (1 + (10% / 100)) = 4928 rubles per month - 2017: 4928 * (1 + (7% / 100)) = 5273.76 rubles per month

Rent in 2018

To calculate the rent for 2018, we need to apply the percentage increase to the rent in 2017. The rent in 2018 will increase by a certain percentage. However, we don't have the exact percentage increase for 2018. Therefore, we cannot provide an accurate calculation for the rent in 2018 based on the given information.

Please note that the information provided is based on the given data and assumptions. It is always recommended to consult with the relevant authorities or parties involved for accurate and up-to-date information regarding rent increases.
