Question

Jon and Lexi are playing a marble game. According to their rules, 4 points are awarded for each red marble collected and 7 points are awarded for each blue marble collected. Which expression represents Jon's total score if he has r red marbles and b blue marbles? (1 point)

Answer 1

I do believe that they would be in two different expressions like so: (4r)
as well as (7b) then in the end you can add them together 4r+7b.
