Question

Amaya's test scores in Algebra 1 are 78 and 91. She has one more test left and wants to earn a B for the course, which is from 80-89 inclusive. Write a compound inequality to represent the situation.

A) 80 ≤ x ≤ 89
B) 78 < x < 89
C) 80 < x ≤ 91
D) 78 ≤ x < 91

Answer 1

The correct compound inequality that represents Amaya needing to earn a B grade, which is a score from 80 to 89, for her final test score in Algebra 1 would be A) 80 ≤ x ≤ 89.

Step-by-step explanation:

Amaya has test scores in Algebra 1 of 78 and 91 and wishes to earn a B grade, which is defined as a score from 80 to 89 inclusive. To find the range of scores Amaya can get on her final test to achieve a B average, we can write a compound inequality. Given the options, the correct compound inequality to represent Amaya's situation would be A) 80 ≤ x ≤ 89. This is because Amaya needs to score at least an 80, but no more than an 89 on her next test to secure a B in the course.
