Answer 1

I’m not that sure if the numbers you provided are the ones I am supposed to be adding or the x’s in the graph but here’s an answer for both

Numbers: 150
X:10

If I didn’t understand what to add, please let me know

Answer 2

10

The x’s represent just the people, and because the bottom line only represents time it doesn’t affect the amount of people.
