Question

The school auditorium seats 310 people. For a particular performance, all of the seats in the auditorium are reserved. The number of seats reserved for students is 25 more than twice the amount reserved for adults (faculty, staff, and parents). How many seats are reserved for students? How many seats are reserved for adults?

Answer 1

the answer is 215.

Explanation:

Here's the work:

95(2)=190

190+25=215

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

and the number we started of with, which is 95, should be the number of adults. To check this we add 215to 95, which equals to 310.

Answer 2

215

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
