Calculating the Number of Wallpaper Rolls for Room Renovation

To calculate the number of wallpaper rolls purchased for the room renovation, we can use the given information about the total length of wallpaper purchased for the kitchen and the room.

Given: - 6 rolls of wallpaper, each 18 meters long, were purchased for the kitchen. - Several rolls of wallpaper, each 10 meters long, were purchased for the room. - The total length of wallpaper purchased is 198 meters.

Let's denote: - \( x \) as the number of rolls purchased for the room.

We can set up the following equation to represent the total length of wallpaper purchased: \[ 6 \times 18 + 10x = 198 \]

Solving for \( x \): \[ 108 + 10x = 198 \] \[ 10x = 198 - 108 \] \[ 10x = 90 \] \[ x = \frac{90}{10} \] \[ x = 9 \]

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