Answer :
Let the variable r represent the amount of red marbles that Jon has, and the variable b represent the amount of blue marbles that Jon has.
Because 4 points are awarded for each red marble collected, 4 will be the coefficient of the variable r (red marbles).
Because 7 points are awarded for each blue marble collected, 7 will be the coefficient of the variable b (blue marbles).
Therefore, the expression of Jon's total score is
4r + 7b
Hope this helps! :)
