Answer:
26.96 inches of fabrics per person
Step-by-step explanation:
Headband
Number of players = 32
Number of coaches = 2
Total people = 32 + 2 = 34
Total fabrics used for headband = 623.22 inches
Fabrics per person = Total fabrics used for headband / Total people
= 623.22/34
= 18.33 inches per person
Wristband
Number of players = 32
Total fabrics used for wristband = 276.16 inches
Fabrics per person = Total fabrics used for wristband / Number of players
= 276.16 / 32
= 8.63 inches per person
Total fabrics used for headband and wristband for each player = 18.33 inches + 8.63 inches
= 26.96 inches of fabrics per person
