Trevor and marissa have 46 t-shirts to sell if marissa has 6 fewer than trevor how many t-shrits does trevor have

You can do this by subtracting 6 from 46 because Marissa has 6 less than Trevor. Then you split the remaining 40 into two meaning that each person has 20, but then you add the 6 back to Trevor so the answer is TREVOR HAS 26 T-SHIRTS (and Marissa has 20)

Total shirts: 46.
Merissa has 6 fewer than Trevor. So that means Trevor has  26 shirts, because half of 40 is 20. Since Trevor has 6 more  than Merissa, Merissa would have 20 shirts while Trevor has 26. Hope that helps! 

Neither is the answer
