Tickets 4

Stacey is selling tickets to the school play. The tickets are $7 for adults and $5 for children. She sells twice as many adult tickets as children's tickets and brings in a total of $342. How many of each kind of ticket did she sell?

Result

a =  18
b =  36

Solution:


7a + 6b = 342
b = 2a

7a+6b = 342
2a-b = 0

a = 18
b = 36
