Well first the unknown number is the amount of hours she works. That will be x. You will multiply 9.20 by the amount of numbers to make 299. That means the amount of hours times 9.20 has to be greater than or equal to 299. The inequality will look like this
9.20x ≤ 299

Choice A only surveys the first ten students; this is not a complete census.
Choice B surveys all the students in the targeted data group. This is a census.
Choice C only surveys the male students, even though there are female students in his data group. This is not a census.
Choice D only surveys the girls on the soccer team, even though there may be boys on the team as well. This is not a census.
Choice E only surveys his friends in the chorus, even though there may have been people that were not his close friends. This is not a census.
Only choice B is a complete census.
