Stephen is not allowed to watch more than 5 hours of television a week. He watched his favorite show on Monday which was 1 hour long and his favorite Tuesday show which was 1.5 hours long. How many more hours of television can he watch? ( 1 point )

Stephen has already watched 2.5 hours of television (1 + 1.5 = <<2+1.5=3.5>>3.5 hours).

He can only watch a total of 5 hours of television a week, so he can watch 1.5 more hours of TV (5 - 3.5 = <<5-3.5=1.5>>1.5). Answer: \boxed{1.5}.
