A project coordinator is tracking team progress and determines that the number of completed tasks, $a$, plus 4 pending reviews must be 'at most' 15 to meet the weekly deadline. Which algebraic inequality correctly translates the statement: 'Four more than $a$ is at most 15'?

A facility manager is reviewing safety compliance for a storage unit. The regulation states: 'The number of permanent staff ($a$) plus 4 visitors is at most 15.' To prepare a compliance report, match each part of this safety requirement to its corresponding algebraic symbol, expression, or solution value.

A compliance officer is reviewing occupancy limits for a workspace. The regulation states that the number of permanent desks ($a$) plus 4 temporary stations must be at most 15. True or False: In the mathematical translation of this regulation, the phrase 'at most' is represented by the 'greater than or equal to' symbol ($\geq$).

Representing Capacity Limits in Interval Notation

A network administrator is documenting server capacity limits. The policy states that four more than the active servers, $a$, can be at most 15. The solution is $a \leq 11$, which is written in interval notation as $(-\infty, 11]$. To show that the endpoint of 11 is included in this safe range, a square ________ is placed at 11.
