A=adult tickets
c=chlderenticekts
s=sinior tickets

a=c

a+c+s=120
2a+s=120

total made is 1100
12a+6c+10s=1100
sub
a=c
12a+6a+10s=1100
add
18a+10s=1100

multiply first equation by -9 and add to other equation

-18a-9s=-1080
18a+10s=1100 +
0a+s=20

s=20

Answer:

f(x) = 3(0.2)^x

Step-by-step explanation:

The leading coefficient is 3 as  x = 0 gives f(x) = 3.

When x = 1, f(x) = 0.6. so try :

0.6 =3(1.2)^1 = 3.6 so it's not the fiirst choice.

0.6 = 3(0.2)^1 = 0.6 so its last choice.

Check when x = -1:

3(0.2)^-1

= 3/ 0.2

= 15

We can turn this word problem into the following equation:
x^2 + 85 = (x - 17)^2
  x^2 + 85 = x^2 - 34x + 289
           -85                       -85
_______________________
      x^2 = x^2 - 34x + 204                    
     +34x         +34x
_______________________
 x^2 + 34x = x^2 + 204
-x^2             -x^2
____________________
       34x = 204
Divide 34 on both sides
      x = 6.
The number is 6.
