9. In some high school classes, the final grade can be calculated with the expression
0.70 (
𝑄1+𝑄2+𝑄3+𝑄4
4
) + 0.30(𝐸𝑂𝐶), where Q1, Q2, Q3, and Q4 all represent each report
card grade and EOC represents the End of Course Exam grade. If Jane got 85%, 88%,
82%, and a 90% on her report card grades in Algebra, then scored an 84% on her EOC,
which of the following information would you consider true?
a. The average of Jane’s report card grades is exactly 85.8%.
b. The average of Jane’s report card grades makes up 0.70 (or 70%) of her final
grade in the class.
c. Jane’s EOC grade was lower than the average of her report card grades.
d. Jane’s final grade in the class is greater than her EOC grade.
e. Jane’s final grade in the class is less than her EOC grade.

Answers:
1. B, E
2. A, C, E
3. A, D
4. A, B, D, E
5. B, C
6. B, D
7. C, D, E
8. A, C
9. B, C, D
10. Answers may vary, and explanations may vary based on the answer provided. A sample
of one equivalent expression would be −30𝑥 + 54 + 15. It is the same as the original
expression because the only change made was distributing the −6 to the inside of the
parentheses.
11. −20𝑥 + 16. I know this is completely simplified because the two terms in this
expression are not like terms. They are not like terms because one term has a variable
and the other does not.
