Question 1108768
Shureka Washburn has scores of 72, 67, 82, and 79 on her algebra tests.
: 
 a. Use an inequality to find the scores she must make on the final exam to pass the course with an average of 77 or higher, given that the final exam
 counts as two tests.
:
Let x = the score on the final exam
{{{(72+67+82+79+2x)/6}}} => 77
300 + 2x => 6(77)
2x => 462 - 300
2x => 162
x => 162/2
x => 81
