Answer:

215

Step-by-step explanation:

set the student number is x. adult number is y.

accroding to the question: x+y=310, x=25+2y

so 25+2y+y=310,

25+3y=310,

3y=285,

∴y=95, x=215

Answer:

the answer is 215.

Here's the work:

95(2)=190

190+25=215

215 equals the amount of seats that are reserved for kids.
