Answer 1

Let the cost of the video game be x

• Carter sold 9 of his video games online

He got $9x for selling 9 video games

• The next day, he sold 27 video games

He got $27x for selling 27 video games

• He collected a total of $900

According to the above problem, the equation we get is

`9x + 27x = 900 \\ 36x = 900 \\x=(900)/(36)\\ \boxed{ x = 25}`

Therefore, the cost of each video game is $25.
