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 ($\geq$).

An HR manager is reviewing a staffing policy which states: "Four more than the number of interns, $a$, is at most 15." Arrange the following steps in the correct logical order to translate this policy into an inequality and find the final solution in interval notation.

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.
