Tickets at a particular movie theater have different rates for adults and children. On Friday the theater sold 5 adult tickets and 4 child tickets for $98. The next
day, the theater sold 2 adult tickets and 7 children tickets for $77. What is the price for the adult ticket and the price for the child ticket?
Hint: Only create the system of equation.
5a + 4c = 98
2a + 7c = 77
