# Apartments

Apartment on the first floor was 10% more expensive than the same apartment on the second floor. The difference was 105 Kc annually. Calculate the annual rent of the apartment in the first floor and from apartment on the second floor.

x =  1155
y =  1050

### Step-by-step explanation:

x = 1.1 y
x-y = 105

x = 1.1•y
x-y = 105

x-1.1y = 0
x-y = 105

x = 1155
y = 1050
