If three adults and two children go to the movies, it costs $33.50. if one adult and four children go to the movies, it costs $30.50. what is the cost of one adult movie ticket?

$5.80
$6.40
$7.30

  $7.30

Step-by-step explanation:

The problem statement gives rise to two equations:

If we double the first equation and subtract the second, we have ...

  2(3a +2c) -(1a +4c) = 2(33.50) -(30.50)
