Answer:
She needs a 96
Her average score now is: 91
Step-by-step explanation:
She needs a total of 460 points. She has already taken 4 of the 5 tests, and earned
85 + 93 + 89 + 97 = 364 points, so she needs
460 - 364 = 96 points
Her average score now is the sum of her scores, divided by the number of tests she has taken, which is...
364/4 = 91
