Answer 5

It says that four points are awarded when you have a red marble. Jon has r red marbles. SO that would be 4*r. It also says that you get seven points when you get a blue marble. Jon also has b blue marbles. SO that would give us 7*b. Later you just add them together to get his total points. :)
