If I got 72% on an interim worth 30 percent what do I need to get on the exam worth 30% and the other work worth 40% to get an 80% overall in the course?

Question

The summary is the question.

Answer 1

72(.3)=21.6

 

80-21.6=58.4

 

You need 58.4/70 total points to get an 80%. 

 

You can divide it up in many different ways from that. Just multiply your score by the percentage it's worth to find the "points."

 

X = 30% test

Y = 40% test

 

X(.3) + Y(.4) MUST EQUAL 58.4 to get a final overall score of 80%
