That's completely up to the teacher, and
it can be different in different classes.
C plus is between 3 and 3.2. C = 75% 0% < Plus < 5% 75%+0% < C Plus < 75%+5% 75 < C Plus < 80% 75%*4 < C Plus < 80% * 4 (3/4)*4 < C Plus < (4/5) * 4 3 < C Plus < 16/5 3 < C Plus < 3.2
75
75 + 5 = 80
The sum of 75 plus 5 is 80.
-15+c+5 = 75 c = 75+15-5 c = 85
A C plus is any grade between 75 and 79. B minus would then be anything from an 80 to an 84, and so on and so forth.
190
no
They add up to 305
80 = 3y + 2y + 4 + 1 80 = 5y + 5 80 - 5 = 5y + 5 - 5 75 = 5y 75 / 5 = 5y / 5 15 = y
If a + b + c + d + 80 + 90 = 100, then a + b + c + d = -70.
It can really depend on the teacher, or person grading the paper, test, project, etc... but usually somewhere between 75% and 80%
