OK SO this is my report card, not my final. I have 2 more coming out so all three add up to my final. how much would i need in my classes to have an average of 90 smt for my FINAL report card?? pls send help

Answer:
90 times 3 is 270
270- 71 ( the average grade you have now)= 199
the 2 more report card average grade has to add up to 199 for you to get a 90.
