Question 784023
It depends on the number of quizzes you have taken in the past.
For example, if you took 3 quizzes and get an average of 62, then your new average should be (3*62+72) / (3+1) = 64.5.
However, if you took 10 quizzes and get a 62 average, then your new average is (10*62+72) / (10+1）= 62.9.
