At Cinemania Movie Theater, movie tickets for a family of 2 adults and 3 children cost $28. Tickets for a family
of 1 adult and 2 children cost $22. How much does an
adult ticket and a child ticket cost?
Oa= 2 + 1
c= 3 + 2
O2a + 3c = 22
a + 2c = 28
O2 + a +3+ c = 28
1 + a + 2 + c = 22
O2a + 3c = 28
a + 2c = 22
