Total number of people including players and coach is, T = 37 + 4 = 41.
Total fabric used for making headbands is, h = 813.44 inches.
So, amount of fabric used for each person is :
[tex]F_h = \dfrac{813.44}{41}\\\\F_h = 19.84\ inches[/tex]
Total fabric used for making wristband is : w = 358.16 inches.
Amount of fabric used for each person is :
[tex]F_w = \dfrac{358.16}{41}\\\\F_w = 8.74 \ inches[/tex]
Hence, this is the required solution.
