Question

Aaron has scores of 100,80,88,92 in his grade book. He wants to have an average of 86%. What’s the minimum score on the next test that Aaron can get?

Answer 1

100 + 80 + 88 + 92 = 360

360 / 4 = 90

86 * 5 = 430

430 - 360 = 70

Answer = 70

100 + 80 + 88 + 92 + 70 = 430

430 / 5 = 86

Hope this helped☺☺
