So you would just need to "group by" table and use another aggregate function to sum them up. I bet you can find that function pretty easily.

SELECT table, sum(people)
FROM Tables
GROUP BY table

All aggregate functions (sum, max, min, avg, etc) must include a GROUP BY including all columns up-to the aggregate.

If this is a school assignment, I suggest you crack the books and spend time in the lab.
