percentage
posted by math on .
a student has an avg of 57%. he has 2 test left which was are both worth 5% and 1 assigment worth 1 %. he also has 1 one big asigment worth 5%. how much would he need minimun in all these to get a 80% avg by the end of it?

If his average at this time is 57%, that is not passing. If he/she were in my class, there is no way to finish with an 80%, even with perfect scores on the remaining 16%.
