Luther wanted to help her get started, so he gave his cousin 17 lunch boxes from his collection. How many lunch boxes does Luther have left in his collection?

Answer 1

For this case we have the following lunch boxes

12 from superhero

19 from outer space

26 from rock bands

A total of: 12+19+26= 57 lunch boxes

And he gave to his cousin 17 lunch boxes so then the remaining are:

57-17= 40 lunch boxes
