Answer: There are 31 chairs that can be upholstered with 4 bolts of fabric.
Step-by-step explanation:
Since we have given that
[tex]1\ m^2=10.7639\ ft^2[/tex]
Volume = 273.5 m²
Number of bolts of fabric = 4
So, Total volume would be
[tex]273.5\times 4\\\\=1094\ ft^2[/tex]
Since 34.7 sq. ft of fabric is needed to upholster one chair.
So, the number of chairs that can be upholstered with 4 bolts of fabric would be
[tex]\dfrac{1094}{34.7}\\\\=31.53\\\\\approx 31[/tex]
Hence, there are 31 chairs that can be upholstered with 4 bolts of fabric.
