Question

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?

Answer 1

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
