Answer:
Headband: 15.98 in.
Wristband: 8.63 in.
Step-by-step explanation:
In this problem, we call:
h = the amount of fabric used for each headband
w = the amount of fabric used for each wristband
We are told that:
Sean uses 671.16 in at on headbands for 39 players and three coaches, so the total number of headbands made is 42
Therefore, we can write
[tex]671.16 = 42 h[/tex]
And solving for h, we find
[tex]h=\frac{671.16}{42}=15.98 in.[/tex]
Then we also know that Sean uses 336.57 in the fabric on wristbands just for the players, so he produced 39 wristbands; so we can write:
[tex]336.57 = 39w[/tex]
And solving for w,
[tex]w=\frac{336.57}{39}=8.63 in.[/tex]
