Answer 4

well you're adding the two point amounts, the ones for red marbles and the ones for blue marbles

Answer 5

You could plug in some numbers to see if your answer makes sense :)
Let's say he collected `2 red marbles` and `2 blue marbles`.

Hmm red marbles are 4 points each, so that's 8 points for the red.
Blue marbles are 3 points each, so that's 6 points for the blue.
Gives us a total of 14 points.

If we use your formula in D,
7(2red)(2blue)=28
Woops! Doesn't seem to work.
