For his fourteenth birthday, Mohammed Jassim decided to inivite a number of his friends. He decided to take them out for a day of fun to the mall near where he lives.

Mohammed researched the catering companies in his area. He chose two: Catering R Us and All Things Catered 4 U. He is trying to decide between the two catering companies, using the algebra he learned in class.

Option 1: Catering R Us charges a fee of 800 and 15 AED per person.

800+15x

Option 2: All Things Catered 4 U charges 200 AED fee and 30 AED per person.

200+30x
