Question

Jake has a 95 average in math after 4 quizzes. Then he got 0 on the next quiz after being absent. There are 2 more quizzes. What average grade does he need on these last 2 quizzes to keep his average at least 85?

Answer 1

I think it is 60 because if you multiply 95 by 5 ( because he took five tests) you will get 475 and next multiply seven by 85 and you will get 595. Now subtract 595-475= to 120 and divide it by 2 ( because he has two extra test) and you will get 60. So the average of the 2 tests must be 60 or higher.
