In a sociology course, the professor informed the students of a recent exam ratio of 9:7:2 for As, Bs , and Cs. If 72 students scoring C or better completed the exam l, how many students received Bs?

28

Step-by-step explanation:

To solve this, I would first add up the total of the numbers in the ratio.

9 + 7 + 2 = 18

Then, I would divide 72 by that number.

72/18 = 4.

Finally, I would multiply that quotient by 7 because 7 is the number in the ratio for B's.

4 x 7 = 28

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
