Answer:
No
Step-by-step explanation:
This is because if the negative is in parenthesis, then the negative is a part of the number being repeatedly multiplied. If it is not in parenthesis, then it is attached after the number is multiplied by itself.
So,
Her average so far is the sum of the five scores divided by the number of tests she has taken so far.
(87 + 81 + 85 + 90 + 78)/5 = 84.2
(87 + 81 + 85 + 90 + 78)/5 < 85 :(
She will not get into that college if she doesn't increase her average on the last test.
85 - 84.2 = 0.8
0.8(5) = 4.0
On her last test, she needs to score 4 points higher than her current average in order to get into the college.
84.2 + 4 = 88.2
Jessica needs to score at least 88.2 on her last test.
