Problema Solution
A theater sold 762 tickets. An adult ticket costs $7.00 and a childs ticket costs $4.50. In all, $4959.00 was taken in. How many of each kind of ticket were sold?
Answer provided by our tutors
Introducing the variables c for child and a for adult, we can obtain two simultaneous equations,
7a + 4.5c = 4959
a + c = 762
Solving both we obtain a = 612, b = 150
