Question

So i need help on one of my homework questions. The problem is, On his first 2 tests Nate`s average score was 80 percent. On his next 3 tests Nate`s average score was 90 percent. What was his average score for all 5 tests? I need help on how to solve this.

Answer 1

His average for all 5 tests would by 86% because 80 + 80 = 160 and 160 + (90 x 3) = 430 and 430 divided by 5 = 86%.
