Answer 2

I posted it not too long ago, but it's still way far down there.

Answer 3

The total score on the first 4 quizzes is given by multiplying the average score by 4:
Total score for first 4 quizzes = 79 * 4
Total score needed for first 5 quizzes = 81 * 5
Score needed for the 5th quiz = (81 * 5) - (79 * 4) = you can calculate.

Thanks. can you help me with a few more?
