Estimating the area:

$x = (20 * 8)(13 * 8) \\ x = 264$
Calculating wallpaper:

$x = (264 * 1.05) / 35 \\ x = 7.92 \\ x = 8$
we round up here because they will need a full roll to complete the room. Since they can't buy 7.92 rolls, they must buy 8.

Calculating cost:

$x = 8(31.48) + 31.48(0.0825) \\ x = 254.44$
