Well we know it’s not C because it’s wording hints the number line would be going the other way and we see the closed circle so that means that we are talking about something that is 16 OR less not less THAN 16 so it can’t be B that leaves A D and E. I’m pretty sure it’s not A since that is talking about an exact amount not that amount or less than so that narrows it down to D and ( if you can mark more than one) /or ( if you can only mark one) E. Hoped this helped! I would also recommend using other resources for confirmation.
Explanation: the number line shows any number less than 16, the filled in circle also means including 16. So it becomes any number 16 or less. So in both of the scenarios the max number of either students or dollars has to be 16.
