PLZ HELP MEEEEEEEEEEEEEEEE

Answer 1

D. 97 points.


Hope this helps

Answer 2

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

she needs at least a 97

Answer is D
