Answer:
40 students are going to the park.
Explanation:
You total is $1325 and there is a fee of 25 dollars for large groups.
So you subtract the $25 from the total $1325 to get $1300.
Then you see its $30 per adult, and 10 adults are going, which is $300.
SO you subtract $300 from $1300 to get $1000.'
Lastly, you divide 25 by 1000, to get 40. You do this to calculate how many students are going. When you check your work you do:
30 x 10 to get 300 + 25(flat fee) + 1000 and you get $1325
