A: adults
C: children

3A+4C = $132
2A+3C= $94

2A+3C=$94
2A+3C-3C= 94-3C
2A= 94-3C
2A/2= (94-3C)/2
A= 94/2-3C/2
so, 3(47-3C/2)+4C=$132
C=$18 price of the children ticket

and by using 2A+3C=$94, C=18
2A+3*18=94
2A=40 ..... A=$20 price of the adults ticket
Good luck

<span>|7x-7|+3 = 4x+1  ⇒⇒⇒ add (-3) to both sides
</span>
<span>∴ |7x-7| = 4x - 2
</span>
According to the absolute rule
∴ 7x - 7 = 4x - 2    OR    -(7x - 7) = 4x - 2                                 
    7x - 4x = 7 - 2      l     7x - 7 = -4x + 2                              
   3x = 5                   l     7x + 4x = 2 + 7                                         
  x = 5/3                   l     11 x = 9  ⇒⇒⇒  x = 9/11

∴ x = 5/3  and  9/11


So, the correct answer is option <span>B. 5/3 and 9/11</span>
