Question

You want to average at least 90% on your algebra quizzes. So far, you have scored 93%, 97% ,81% and 89% on your quizzes. It is possible for you to raise your quizz average to 97% if only one more quiz is added? Explain?

Answer 1

Write an equation that satisfies this:

`(93+97+81+89+x)/5=97`

Solve:

`(360+x)/5=97`

`360+x=485`

`x=125`

So technically it is possible with bonus points, but no, in a regular test out of 100, it is not.
