If you are looking at the total of just people who have just bikes that's 40 and people who have just skateboards that's 10 so 30 but if its the total of bikes that's 72 and the total of skateboards that's 42 which is also 30. My best guess seeing as i don't know what math class you are in is 30.
Answer:
{x:x is a multiple of 3, x ≤ 15}

So, option B is your answer.
Hope this helps!
