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

92

Step-by-step 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
