Theresa earned scores of 88 points, 84 points, 88 points, and 91 points on four tests. what is the lowest score she can get on the fifth test and still finish with an average score of 90 points? a. 94 points b.95 points c.96 points d.97 points plz m

90 x 5 = 450 ( total points for  tests)

88 + 84 + 88 + 91 = 351 ( total of 4 tests)

450 - 351 = 99

 if she scores a 97 she would have 88+84+88+91+97 = 448. 448/5 = 89.6 which would round to a 90
