12 out of 50 seventh graders
said they would be willing to pay
between $21-$30 dollars for a
class trip. If there are 350
students in seventh grade,
about how many would go oh
the trip if it cost $30?

84 students

Explanation:

Of each 50 — 12 will go.     350/50= 7.    7*12=84

84 students would go on the trip if it cost $30.

Explanation:

If there are 350 students and 12 out of 50 students said they'd be willing to pay, we just have to divide 350 by 50 and then multiply that number by 12.

350 divided by 50 is 7. 7 multiplied by 12 is 84.
