Respuesta :

Idk what it has to do with simplifying but what I would do is multiply 1 times 3. That gives u 3. Then add Ben's one hour and Brooke's 3 hours together. That gives u 4 hours total.

Time Spent by Ben while cleaning his room=1 hour

⇒ Time Spent by Ben's Sister while cleaning his room=3×1 hour=3 hour--------------[As, it is given that, Ben's sister spent 3 times as many hours that ben spent while cleaning her room].

⇒Total Number of Hours that Ben and his sister spend cleaning their rooms altogether

           =1 Hour +3 Hour

           =4 Hour

→First,we have evaluated , the time spend by ben's sister while cleaning her Room.
