Please help!!! i really need some help on this :( I'll make you Brainliest!!!


A student scored 78 and 92 on his first two quizzes. Use the compound inequality to find the possible values for a third quiz score that would give him an average between 80 and 85.


a: 78 ≤ x ≤ 92

b: 75 ≤ x ≤ 85

c: 70 ≤ x ≤ 85

d: 80 ≤ x ≤ 85

78+92=170
170/2=85
 
his current average is 85% so id go with C knowing that if his next quiz he got at least a 70, his average would be 80%
