Question

The Drama Club sold 450 tickets for the spring play. An adult ticket cost $5 and a student ticket cost $3. Total ticket sales equaled $1900. Find out how many adult and student tickets the club sold.

Answer 1

$x+y=450$
$5x+3y=1900$


$x=450-y$
$5(450-y)+3y=1900$

$-2y+2250=1900$
$-2y=-350$
$y=175$
$x=275$
