Aticket to a museum costs $8. a ticket to the dinosaur exhibit costs $5. the expression 8n+5n represents the cost in dollars for n people to visit the museum and the exhibit. what is a simpler form of the expression 8n+5n

The equation which represents the people that want to visit the museum and the exhibit is 8n+5n.
As you can see, the variable n is present in both terms 8n and 5n of the equation, so we can now factor the equation. You create parenthesis in which you put inside 8+5 and then you throw the variable n outside the parenthesis, and you get at last:
8n + 5n = (8+5)n

Hope this helps! :D
