Question

booker owns 85 video games.he has 3 shelves to put the game on. each shelve can hold 40 video games how many more video games does he have room for?

Answer 1

First lets see how much room there is for holding video games.
There are 3 shelves that can hold 40 video games each, that is:
3*40 = 120
so we can hold 120 video games total.
If now there are 85 video games, how many we can hold still? That is:
120 - 85 = 35
So we still can hold 35 more video games.
