Answer 2

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

Explanation:

Relationships between two variables is proportional if their ratios are equivalent.

In 2010, the school paid $1,260 for 84 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 =
`1260:84=15:1`

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 =
`1050:70=15:1`

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 =
`1,395:93=15:1`

As
`1260:84=1260:84=1,395:93=15:1`,

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