Answer:
Option D is right
Step-by-step explanation:
Given that Theresa earned scores of 88 points, 84 points, 88 points, and 91 points on four tests
Thus total points she got in 4 tests = 88+84+88+91
= 351
If she has to obtain average score of 90 points,
then we have for 5 tests average should be 90
Hence total marks required = no of test *average
=5(90) =450
In 4 tests total =351
Minimum marks she must get in 5th test to get average score of 90 and above is
=450-351
=99
