At the movie theatre, child admission is $6.20 and adult admission is $9.30 . On Monday, 157 tickets were sold for a total sales
of $1178.00 . How many adult tickets were sold that day?
1 answer:
C = child tickets
a= adult tickets
c + a = 157
6.20c + 9.30a = 1178.00
6.20c + 9.30a = 1178.00
-6.20c -6.20a = -973.40
3.10a = 204.60
a = 66 adult tickets
c + 66 = 157
-66. -66
c= 91 child tickets
