Answer:
Choice A.
Step-by-step explanation:
Let x = price of a helmet, y = price of a bat, z = price of a ball.
Company A can provide 9 helmets, 6 bats, and 12 balls for $525.
9x + 6y + 12z = 525
Company B can provide 10 helmets, 8 bats, and 10 balls for $600.
10x + 8y + 10z = 600
Company C can provide 8 helmets, 5 bats, and 15 balls for $500.
8x + 5y + 15z = 500
Answer: Choice A.
Answer:
The correct option is A.
Step-by-step explanation:
Let the price of a helmet is x, the price of a bat is y and the price of a ball is z.
It is given that Company A can provide 9 helmets, 6 bats, and 12 balls for $525. The equation for Company A is
[tex]9x+6y+12x=525[/tex]
It is given that Company B can provide 10 helmets, 8 bats, and 10 balls for $600. The equation for Company B is
[tex]10x+8y+10x=600[/tex]
It is given that Company C can provide 8 helmets, 5 bats, and 15 balls for $500. The equation for Company C is
[tex]8x+5y+15x=500[/tex]
The system of equations is
[tex]9x+6y+12x=525[/tex]
[tex]10x+8y+10x=600[/tex]
[tex]8x+5y+15x=500[/tex]
Therefore the correct option is A.
