Mrs. Franklin purchased 27 child tickets and 23 adult tickets, which cost a total of $1,056. Mr. Patrick purchased 27 child tickets and 30 adult tickets, paying a total of $1,287. What are the ticket prices?

Answer 1

1 Adult ticket=$35

1 Children ticket=$20

Explanation:

21C+15A=945

6C+6A=330

we find adult tickets first

42C+30A=1890

42C+42A=2310

12A=420

A=35

we will find children ticket next

42c+30a=1890

30c+30a=1650

12c=240

C=20
