Answer:
24.33 inches
Step-by-step explanation:
inches of fabric on headbands = 648.62 inches
39 players and 2 couches = 41 people
Inches of fabrics per person = Total headbands inches / number of people
= 648.62 inches / 41
= 15.82 inches per person
Inches of fabrics used for headbands per person = 15.82 inches
inches of fabric on wristbands = 331.89 inches
Used for players alone
Inches of fabrics for wristband pee person = Total inches of fabrics for wristband / number of people
= 331.89 inches / 39 players
= 8.51 inches
Inches of fabrics used for wristband per person = 15.82 inches
How much fabric was used on a headband and wristband for each player?
= Inches of fabrics used for headbands per person + Inches of fabrics used for wristband per person
= 15.82 inches + 8.51 inches
= 24.33 inches
Inches of fabrics used on headband and wristband for each player is 24.33 inches
