Let's use variables to represent the number of games that Marcus and Josh own.
We know that Kyle has 8 games, so the total number of games owned by Marcus and Josh must be 28 - 8 = 20.
We also know that Josh has 4 times as many games as Marcus. So, let's say Marcus has x games. Then, Josh has 4x games.
The total number of games owned by Marcus and Josh is x + 4x = 5x. We know that 5x = 20, since the total number of games owned by Marcus and Josh is 20.
Solving for x, we get x = 4.
So, Marcus has 4 games and Josh has 4x4 = 16 games.
Therefore, the answer is B) 16 games.
