Question 1036082: I'm having problems getting the numbers into a formula of the movie cinema charges 7.75 for adult tickets, and 4.75 for children tickets. Total of 6 family
members went for a total cost of 34.50 how many adult tickets were sold, and how many children tickets were sold? I know the answer, but do not know how to show it in a formula.
Answer by fractalier(6550)   (Show Source):
You can put this solution on YOUR website! Call the numbers of adult and children's tickets, a and c. Then we write
a + c = 6 and the value equation is
7.75a + 4.75c = 34.50
You just combine these by elimination (or substitution) and arrive at your answer.
