You scored an 81% BECAUSE
57/70 = 0.814286 and
171/210 = 0.814286
171 (57 each worth 3 points) divided by 210 (70 each worth 3 points) = 0.814286
each question, if equal points per question, is 1/1.10 = 0.9 points; you need to answer 77 questions out of 110 correctly to score a 70
2 * (50 - x) = 70 50 - x = 35 x = 15 You can miss 15 questions.
If there is no curve, each question is worth around 1.48 points, but if simply divide 60/70 you get 85.714%. I think so,but my teacher told me it is a B+.
-57 is greater than -70
70 percent of 60 is 42. The points don't enter into it.

It depends on how many points each question is worth. If they are worth 1 point, 30, 2 points, 15, etc...

70 - 57 = 13
70% of 57 is 39.9.
-57 is greater than -70

57/100 = x/70. Cross multiply; 3990=100x x=3990/100. 57 % of 70 is 3990/100 or 39.9.
39.9
1(95-x)=70 95x=70 x 25x
3990
