Question
ticket for a concert cost $5.00 for adults, $3.00 for children and $2.00 for senior citizens. Revenue was $500.00 for 180 tickets. 10 times more adults than children attended. How many senior tickets were sold?
Answers
a + c + s = 180
5a + 3c + 2s = 500
a = 10c
replace 'a' with '10c' in the first two equations.
This will give you two equations in two variables. You can then use the elimination/addition method to solve.
