ANSWER
[tex]3n\text{ + 8 }\leq\text{ 16}[/tex]EXPLANATION
We want to write the sentence as an inequality.
We have:
The sum of 3 times a number n and 8 is at most 16.
3 times a number n is 3 * n i.e. 3n
Adding that to 8 would yield:
3n + 8
That is at most 16.
This means that it is less than or equal to 16.
That is:
[tex]3n\text{ + 8 }\leq\text{ 16}[/tex]
