[tex]b)\text{ x}\leq1095[/tex]
Explanation
Step 1
Let x represents the maximum number of people who can be transported at the same time,
as we know the total number of elevators and the number of people per elevator,we can use multiplication to find the total
hence
[tex]\begin{gathered} \text{total people= number of elevators }\cdot rate \\ \text{replacing} \\ \text{total people=73 elevators}\cdot15\frac{\text{people}}{\text{elevator}} \\ \text{total people=}1095 \end{gathered}[/tex]
it means the maximum number of people ( x) must be equal or smaller than 1095
in math terms it is
[tex]\begin{gathered} \text{maximum people}=x \\ \text{total people}\leq1095 \\ \text{hence} \\ x\leq1095 \end{gathered}[/tex]
so, the answer is
[tex]b)\text{ x}\leq1095[/tex]
I hope this helps you
