Tickets to a local movie were sold at $3.00 for adults and $1.50 for students. if 170 tickets were sold for a total of $480.00, how many adult tickets were sold

Respuesta :

$3X+$1.5Y = 480

X+Y=170
Y=170-X

3X+1.5(170-X) = 480
3X + 255 - 1.5X = 480
1.5X + 255 = 480
1.5X = 225
X= 150 Adult Tickets.
