Lucas is making accessories for the soccer team, he uses 685.85 of fabric on headbands for 41 players and 2 coaches. He also uses 353.83 inches of fabric on wristbands for the just the players. How much fabric was used on a headband and wristband for each player?

Answers

15.95 inches fabric was used on headband and 8.63 inches fabric was used on wristband of each player.

Step-by-step explanation:

Fabric used for headbands = 685.85 inches

No. of players = 41

No. of coaches = 2

Total = 41+2 = 43

Fabric used for one headband = $(Fabric\ used)/(Total)$

Fabric used for one headband = $(685.85)/(43) = 15.95\ inches$

Fabric used for wristbands = 353.83 inches

No. of players = 41

Fabric used for one wristband = $(Fabric\ used)/(No.\ of\ players)$

Fabric used for one wristband = $(353.83)/(41) = 8.63\ inches$

15.95 inches fabric was used on headband and 8.63 inches fabric was used on wristband of each player.
