Question

Each school year, the seventh graders who study Life Science participate in a special field trip to the city zoo. In

2010, the school paid $1,260 for 84 students to enter the zoo. In 2011, the school paid $1,050 for 70 students to
enter the zoo. In 2012, the school paid $1,395 for 93 students to enter the zoo.
a. Is the price the school pays each year in entrance fees proportional to the number of students entering the
zoo?
b.
Explain why or why not.
c.
Identify the constant of proportionality and explain what it means in the context of this situation.

Answer 1

A. Yes

B. Yes the price every year are proportional to each other because for every value I got the number 15. I divided 1,260 by 84 and got 15. I divided 1,050 by 70 and also got 15. I finally divided 1,395 by 93 and I also got 15. So, this is my explanation on why all 3 values are proportional to each other.

C. The constant of proportionality is, 15. The constant proportionality tells us how much money the school wastes on each student.
