Calculation of Wallpaper Rolls for Room Repair

To calculate the number of wallpaper rolls purchased for the room repair, we can use the given information that a total of 198 meters of wallpaper were purchased, with 6 rolls of 18 meters each for the kitchen and several rolls of 10 meters each for the room.

Let's denote: - Number of rolls for the kitchen as x - Number of rolls for the room as y

We can create the following equations based on the given information: 1. For the kitchen: 6 rolls * 18 meters/roll = 108 meters 2. For the room: y rolls * 10 meters/roll = 10y meters

The total length of wallpaper purchased is 198 meters, so we have the equation: 108 meters (kitchen) + 10y meters (room) = 198 meters

Solving for the Number of Rolls for the Room

By solving the equation 108 + 10y = 198, we can find the number of rolls purchased for the room.

108 + 10y = 198 10y = 198 - 108 10y = 90 y = 90 / 10 y = 9

Answer

Therefore, the number of rolls purchased for the room repair is 9.
