Question

I need help dont just add both numbers ill give extra hundrend after you answer

Answer 1

Answer:

28

Step-by-step explanation:

According to the question,

2 helmets and 1 football cost $80, while 1 helmet and 2 football cost $76

Let x represent cost of football and let y equal cost of helmet.

Write the system of equations,

$x +2 y = 80$

$2x + y = 76$

Eliminate the x variable by multiplying the top equation by -2

$- 2x - 4y = - 160$

$2x + y = 76$

Add both equations.

$- 3y = - 84$

$y = 28$

So one helmet cost $28
