In 2011, the school paid $1,050 for 70 students to enter the zoo.

Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = [tex]1050:70=15:1[/tex]

In 2012, the school paid $1,395 for 93 students to enter the zoo.

Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = [tex]1,395:93=15:1[/tex]

As [tex]1260:84=1260:84=1,395:93=15:1[/tex],

the price the school pays each year in entrance fees is proportional to the number of students entering the zoo.
