If we pretend that x represents shirts and y represents shorts than they represent these equations perfectly. First of all we have to see that we are not subtracting anything so there really isn't any reason to use negative symbols. Anyway looking at these equations if we get 4 shirts (x) and one (shorts)(y) then the total should be $38. Same for Justine's equation 4 shirts (x) and 3 shorts(y) the total should match her $71.5
