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 and his favorite Tuesday show which was 1.5 hours long. How many more hours of television can he watch?

2.5h = 5; Stephen can watch 2 more hours this week.

h + 1 + 1.5 = 5; Stephen can watch 2.5 more hours this week.

h + 5 = 1 + 1.5; Stephen can watch 2.5 more hours this week.

h - 1 - 1.5 = 5; Stephen can watch 7 more hours this week

None of the provided equations accurately represent the problem and the question asked.

To find out how many more hours of television Stephen can watch, we need to subtract the total number of hours he has already watched from the maximum allowed hours.

Total hours watched = 1 + 1.5 = 2.5 hours.
Maximum allowed hours = 5 hours.

So, Stephen can watch 5 - 2.5 = 2.5 more hours of television.
