You and your friend play an arcade game. you get 5 points for every 9 points your friend scores. you score 320 points less than your friend. how many points did you each score?

Each scored 80 shots

My friend scored in total=720 points

I scored in total=400 points

Step-by-step explanation:

Each time you score you gain 4 less points than your friend so, you can do this equation

9X-320=5X> 9X=Points scored by your friend every shot

X=80                             5X=Points scored by you every shot

X=amount of times each scored

9·80=720--->Your friend

5·80=400> You

720-400=320 So its ok
