Question 1025529: you scored a 72, 70, 83, and a 92 in your math class. you have one more test before the end of the year. write an inequality that will determine what possible score you need to make on the next test so that your final average is at least an 80?

To average more than 80 on five tests, the sum of the scores must be greater than
(5*80)=400.
.
Let x be the score on the final test.
.
72+70+83+92+x>400
317+x>400
x>83
.
