Casey had 24 video games.( B) Casey had 15 video games.( C) Casey had 12 video games( D) Casey had 48 video games.

Answer 1

D

Explanation:

Casey has some number of video games at the beginning called x. He sells half which is 1/2 x. Then he buys 3 more so 1/2 x + 3. This is equal to his current amount which is 27. So 1/2 x + 3 = 27. Solve for x.

1/2 x + 3 = 27

1/2 x =24

x = 48
