No because she added 2 instead of 2398. She thought the 2 was separate because of the comma separating the 2 thousand. She also made a mistake by thinking she could add easily by adding 2 to 2398 to make 2400.
let us repersent the number of student tickets, then 's + 20' is repersenting the number of adult tickets.
The equation for the total tickets can be experssed as the following:
4.00 * s + 8.00 * ( s + 20 ) = 880.00
solving for 's=60', there were 60 student tickets.
60 + 20 = 80
there were 80 adult tickets.

Answer:
(2, -39)
Step-by-step explanation:
f(x)=-3(x+2)^2+9
f(2)=-3(2+2)^2+9
f(2)=-3(4)^2+9
f(2)=-3(4)(4)+9
f(2)=-3(16)+9
f(2)=-48+9
f(2)=-39
