Answer:
the answer to the second one is (205 - 15)/2.
Lilly has 110.
Severus has 95.
Explanation:
Because 205-15 = 190 so if you divide that by 2 then you will get the amount that Severus had which is 95 meaning that Lilly also has 95 but since she has 15 points higher then she has 110 so 95+110=205.
