Uh...Yea... Sorry about this, but I"m trying to study and I need someone to walk me through, missed a lot of school. fyi, when there's a / its under the entire string before it until you hit the inequality symbol.

Question

Tony Bowled 135 and 145 in his first two games. Write and solve a compound inequality to find the possible values for a third game that would give him an average between 120 and 130, inclusive.

1. 120 <= 135+145+n/3<=145; 120<=n<=140

2. 135 <= 120+140+n/3<=145; 80<=n<=85

3. 120 <= 135+145+n/3<130; 80<n<110

4. 120 <= 135+145+n/3<=130; 80<=n<=110

Yea...I get the general idea on this, but my teacher is on a field trip today so I haven't been able to ask any questions.
