Question

To average a 90% after scoring an 82% and 96%, what do you need to score?

Answer 1

92

Explanation:

one easy way to do it is to break down the process of averaging numbers. 90*3= the two nums you have + unknown

the equation you write can be like

90=(82+96+ incog)/3

90*3=(82+96+ incog)

270=178+ incog

270-178= incog

incog=92
