Answer:
Booker has room for 35 new games.
Step-by-step explanation:
multiply the amount of games that can be held on one bookshelf by 3.
40 times 3 = 120
he has room for 120 games, so subtract the amount of video games he already has with the amount he has room for.
120 - 85 = 35
Booker has room for 35 new games.
