Answer:

Ivan answered both questions worth 4 points and 5 questions worth 2 points correctly

Step-by-step explanation:

If there are 6 questions worth 2 points then that equals 12 points

Then 2 questions worth 4 points each equals 8 points.

12+8= 20 so thats 20 total points. If he only got 18 then you subtract 2 and thats the worth of one point.


So, the 2 questions worth 4 points is 8 total points plus 5 questions worth 2 each is 10 total points = 18 points.
