Question

Professor Chang will give a student in her algebra class an A if his or her final score is at least 93, a B if the score is between 84 and 92, inclusive, and a C if the score is between 75 and 83, inclusive. Any student with a score between 66 and 74, inclusive, will receive a D, and anyone with a score at or below 65 will fail with a grade of an F. Letting x represent a student's grade, write a series of five inequalities corresponding to the possible grades given in the class

Answer 1

a. x > 93 A
84 ≤ x ≤ 92 B
75 ≤ x ≤ 83 C
66 ≤ x ≤ 74 D
x < 65 F
b. x ≥ 93 A
84 ≤ x < 92 B
75 ≤ x < 83 C
66 ≤ x < 74 D
x ≤ 65 F
c. x ≥ 93 A
84 ≤ x ≤ 92 B
75 ≤ x ≤ 83 C
66 ≤ x ≤ 74 D
x ≤ 65 F
d. x ≥ 93 A
84 ≥ x ≥ 92 B
75 ≥ x ≥ 83 C
66 ≥ x ≥ 74 D
x ≤ 65 F

Answer 2

C or B or the logical choices
i think C
