Answer: 24.5 inches
Step-by-step explanation:
Luca used 587.19 inches for 35 players and 2 coaches:
= 35 + 2
= 37 people.
The inches per person used for headband is:
= 587.19/37
= 15.87 inches
Luca then used 302.05 inches for just players who number 35 to make wristbands. Inches used per player is:
= 302.05/35
= 8.63 inches
Fabric used for each player is therefore:
= 15.87 + 8.63
= 24.5 inches
Answer:
8 chicken, 4 beef
Step-by-step explanation:
No. of chicken: x
No. of beef: y
x + y = 12
x = 12 - y
10x + 14y = 136
10(12 - y) + 14y = 136
120 - 10y + 14y = 136
4y = 16
y = 4
x = 12 - 4
x = 8
