Question 437255
Ann and Sean, paid $208 for concert tickets. They bought twice as many balcony tickets as floor tickets. Balcony tickets cost $15 each and floor cost $22 each. How many of each type of ticket did they purchase ? 
.
Let x = number of floor tickets
then from "They bought twice as many balcony tickets as floor tickets."
2x = number of balcony tickets
.
Our equation comes from:
"Balcony tickets cost $15 each and floor cost $22 each." and the fact that they paied $208:
15(2x) + 22x = 208
30x + 22x = 208
52x = 208
x = 4 (floor tickets)
.
balcony tickets:
2x = 2(4) = 8
