Booker own 85 video games. he has 3 shelves to put the games on. each shelf can hold 40 video games. how many more video games do he have room for

Booker has room for 35 more video games since his 3 shelves (which can hold 40 games each) holds a total of 120. 120-85 = 35

Idon’t exactly understand but i think dbc=rst

If i think this is what your asking, he should look at the grams or pounds/ounces and compare the to their cost then max can identify which one is proportional and which is not ( i think xd)
