Mark and peter went to an arcade where the machines took tokens. marilk played 9 games of ping pong and 5 games of pinball, using a total of 29 tokens. at the same time, peter played 3 games of ping pong and 1 game of pinball using up 7 tokens. write a system of equation to model this situation? how many tokens does each game require?

9x + 5y = 29 (1) and

3x + y = 7 (2)

Each game of ping pong requires 1 number of token and each game of pinball requires 4 number of tokens.

Step-by-step explanation:

Let, each game of ping pong requires x number of tokens and each game of pinball requires y number of tokens.

So, from the given conditions we can write

9x + 5y = 29 (1) and

3x + y = 7 (2)

Now, solving equations (1) and (2) we get,

9x + 5(7 - 3x) = 29

⇒ 35 - 6x = 29

⇒ 6x = 6

⇒ x = 1 token.

Now, putting x = 1 in equation (2) we get,

3 + y = 7

⇒ y = 4 tokens.

So, each game of ping pong requires 1 number of token and each game of pinball requires 4 number of tokens. (Answer)
