There are 1,800 students at a high school. Of the students who have smoked at least one cigarette in the last month, five-eighteenths are twelfth graders. Thirty-five percent of the remaining students are eleventh graders, and the rest are in the ninth and tenth grades. If there are 169 students in the ninth and tenth grades who have smoked at least one cigarette in the last month, how many students in all have smoked at least one cigarette in the last month?

260 students

360 students

50 delegates

35 delegates

These choices do not make sense because 5/18 of 1800 is 500 by itself ???

5/18 of the total smokers are in 12th grade.

You need to find how many smokers there are.

That's not true.

See what it says

Of the students who have smoked at least one cigarette in the last month, five-eighteenths are twelfth graders.

That equals 500 more than all the choices given
